4 good reasons to kill unconscious bandits
Options for the Pally-and-Bandy scenario depends on the group, the ethics imposed on the games, and the actions taken:
If you are role-playing a group where you have imposed a modern sense of ethics on a group of primitivist warriors, then it is probably not a good act and may actually be enough of an ethical blight on his character to require some kind of atonement before advancing.
In a fantasy world with fantasy world ethics its probably not evil. Evil would be the palladin tying him to the horse and dragging him the rest of the way to town.
In an actual primitive society, a society based on martial law in the most literal sense, then the latter might not be considered evil either, given what we know about justice and retribution in primitive societies where the abrogation of law by one individual was far more likely to cause pain and suffering for the collective, thus penalty could be far more harsh; for instance, in our society we sneer at the backwards folk who would cut off a hand of a thief, or even execute an adulterer; but when we consider the effects that such crimes had in a primitive society (i.e., blood feuds, acts of revenge, splintering of collective populations, etc.) it becomes easier to understand how certain crimes had punishments we despise. Remember, we are talking about the types of societies where Menelaus and Agamemnon sacked troy because Helen was something of a tart, or where Tristan and Isolde were sentenced to death due to a violation of trust and oath.
A bit closer to home, consider how commonly the crime of horse theft was considered a capital crime in the american west. It wasn't just that the theft of the horse itself was a capital crime, but that stealing the horse of someone out in the middle of the american desert usually meant their own death or economic disenfranchisment.
Now lets think about the bandits on the road apart from our miranda-rights-handcuffs-and-fair-expedient-trials-system. A bandit on a road isn't just robbing people, or even killing a few pissant commoners. That action constitutes a threat to the society on several layers:
1. It constitutes a political threat to the powers that be. The powers that be have a vested interest in remaining in power. This is important because even in a monarchy the people have no vested interest in obeying a ruler who cannot protect them from common thugs (for a historical example, consider the campaign against the pirates waged by the Roman general Pompey trying to curry favor with the populace). Further more once the offending parties know that the ruling powers are impotent to stop them they can accelerate their crimes, hastening the break down of the system. The break down between a ruler and its subjects constitutes a threat to the very fabric of the rather fragile systems of ancient and medieval society. A threat to commoners on one road by a group of brigands is a threat to all members of the realm.
2. Tangential to this issue of trust between members of the body of commoners and the ruling party is the idea that the threat posed by the brigand usually constitues a threat to the rules and mores of honorable and stable society. DnD is somewhat unrealistic in the idea that any rube who wants can go to the locak smith and plunk down something like 15 coin for a decent blade. No, in actuality an individual who had a sword and armor was likely at some point in the service of a lord or other political entity who failed to retain that individual in his or her provision and control.
3. It constitutes an economic threat by which an individual is robbed not only of his money and mechandise but also of his time, his ability to make his livelyhood during such a time, and a robbery of all the time and investment that individual spent in whatever is stolen. Further more, a primitive agrarian based economy is far more suceptible to disturbances in the economic system than a modern system fully equipped with provisions against such disasters (afterall, one has to assume that the poor schmoe being held up by the bandits for his cps hasn't taken out a bandit-insurance-policy with the local office of Allstate.). Because the damage is more severe to the local economy (that is if the farmer robbed goes hungry, so likely do the merchants who depended on his patronage in a subsistence economy,i.e., say the local pottery maker, or the farm hands) then the crime is more severe.
4. It constitutes a psychic threat to the mind of many to trust in civilization and society itself. Afterall, if two or three men armed with weapons can rob me of my goods and my ability to exist in a meaningfully fulfiling way in this society, what point is there to participating in this society to begin with. Pardon the patronism, but we aren't dealing with sophisticated people here. If the society can't do anything for me, then why support it would have been a reasonable conclusion for an illiterate pre-modern farmer to take.

Now any of that simply relates to the issue of bandits on the road waylaying travelers, and the bandits are simply out to do something like provide food for their hungry children or something. Neutral to Chaotic Neutral at best. Take any of those reasons and sumperimose them and the effects on say, the ubiquitous evil cult poisoning the water supply and offering virgins to demons and you get a whole other level of threats themselves:
Threats to the order of the cosmos, perversions to the essense of humanity, etc. Its the sort of thing that makes the LG law-abiding Lord disgusted enough to round up a posse of so-called do-gooders and put everyone in the lovecraftian subterranean temple complex to the sword no questions asked.
If Goodman Palladin had the ethical foresight for his time to tie the bandits up and take them to a local authority, he probably would have been scolded for taking time out of the busy rulers schedule and the bandits would have been executed anyway. Think of CdG in this case as a labor-saving action for everyone involved. The Palladin gets to the city on time. The Lord can continue overseeing the rulership of his domain without having to oversee the execution of someone Sir Numbskull should have killed anyway. The bandits don't have to stumble behind the palladins horse for two odd days wondering what its going to be like to dance on the gallows tree.
fwiw
guacamole - who hasn't commited a CdG in at least 24 hours...
