That line of thinking will make the Paladin pretty inefficient, which would kinda negate the gods purpose for the Paladin. For example, if the Paladin is tasked with cleansing the land of an Orc tribe. He's up to the task and challenges the tribe to move or cry and move.
A fight ensues. The Paladin kills the tribes warriors to the last one - them being proud warriors, strangers to surrender. Now there's the woman and children. They're as good as dead, having no raiders and hunters to support them. The winter is coming.
The Paladin obviously did the right thing - killed the evil orc warriors who refused to relocate. But no he's condemned the woman and children to die.
I tried to make the example non-farfetched, but whats your opinion? What should've the Paladin do?
Not go out of his way to kill them, but trust that if they deserve to live, they'll be taken care of by the same gods that tasked him with destroying the warriors. If orcs and goblins are just plain evil from birth, that's one thing. If they learn to be evil over time, it's another.
Also, a paladin might be waging a war of justice, but not one of goodness. It might be that the orcs are being pushed into finding new territory because their numbers have grown and so they need to expand. But expansion puts them at odds with human settlements. The humans have a right to the land, but the orcs are forced to invade it and do their orc business, which wouldn't be a problem if it were in the designated "orc territory." If orcs are recognized as controlling a bordered territory, it would be wrong to enter it to start slaying orcs without provocation. However, if the orcs invade human lands for whatever reason, justice demands they be stopped.
Stopping them isn't really a good or evil act. The orcs might not have any real malice against the humans. They just decided that the plot of land is theirs and everything in it belongs to them, because otherwise they'd starve...a position which is pretty much Neutral. The orcs in this example don't really care about hurting humans, but there are humans there, so too bad for them. So when they start raiding for food and goods, and the humans have to oppose them, it's not really a fight against evil. But it's something that a paladin would want to get involved with, because innocent humans are being attacked.
The point is, unless the paladin has a good reason to do otherwise, he should probably avoid killing those who can't defend themselves and who have not themselves committed acts that would warrant punishment. An orc child may be destined to become a despicable monster when he grows up, but he's not yet a monster, and so does not yet deserve punishment. Part of being a good guy is that you don't punish people for things they haven't done.
The paladin's job is to stop evil. If stopping evil means that some orcs are left without fathers, that's unfortunate, but the paladin is the sword-arm of good, and he knows that if the gods wanted him to stop evil without violently destroying it, they'd let him know.
