However, the MM points out that Lizardfolk are known for eating intelligent humanoids. That is likely to be the belief of the majority of the people in the adventuring party at the start of the adventure. It didn't take future knowledge.
Actually, what it says is:
"Although they are omnivores, lizardfolk prefer meat; popular lore holds that lizardfolk prrefer humanoid flesh, but this charge is largely unfounded (though some tribes do eat captives or slain foes)".
Here is something I'm finding interesting in this conversation though. Folks are using the above statement to hold lizardmen up as "evil". Yet a party that kills a captive isn't evil? It strikes me as a terribly contradictory position.
The Lizardman being incapcaitated is metagame knowledge. There is no way for the characters to know for sure if he is unconscious, dead, or faking it without taking a good deal of time to check.
Hardly. It's a heal check. The same standard action it takes a warlock to, for example, let loose an eldritch blast...
Also, the OP clearly stated that the LM was knocked out. That was, based on the OP, known knowledge.
Time they woud be better served preparing for the coming attack. The CN warlock decided to kill the lizardman. We really don't know the warlock's motivation. He could just be mad and taking it out on the lizardman. He could fear that the lizardman is going to wake up and join in the fight making it a threat. He might have decided that the lizardman would just betray them again.
I've never questioned the CN warlocks motivation, so I'm not sure how that's a relevant response to me. I have, exclusively, dealt with the question of whether a LG character would should consider such an act as anything other than evil.
A LG paladin could easily have said "die treacherous cur," chopped off its head, and not broke his alignment by the PHB.
I'm not sure how you come to that conclusion. Minimal research in the PHB turns up statements and comments such as:
"“Good” implies altruism, respect for life, and a concern for the
dignity of sentient beings. Good characters make personal sacrifices
to help others."
and
"“Law” implies honor, trustworthiness, obedience to authority, and
reliability. On the downside, lawfulness can include closemindedness,
reactionary adherence to tradition, judgmentalness,
and a lack of adaptability. Those who consciously promote lawfulness
say that only lawful behavior creates a society in which people
can depend on each other and make the right decisions in full
confidence that others will act as they should."
Again, the only perspective I have maintained in this discussion is the LG perspective. I don't question the CN warlocks actions. He did, pretty much, exactly what I would have expected. However, the LG player isn't CN. Those same actions aren't expected. An old dragon article, I think that was it anyway, had a saying I have always maintained - "it ain't easy being good".
