painandgreed said:My mistake, "aid to suspected attempted murder" then. It's enough reason. Hell, IMC, aid to breaking and entering into a man's house would probably count as reason to kill the halfling. For that matter, acting upon suspected theft against a friend or ally out of honor is probably enough. Death comes cheap*, even for good** characters to deal out. In a world with proof of just afterlife and where it is possible to be raised, "death" is a completly separate punishment from "death without possiblity of being raised".
Dealing out death on suspicion isn't justice, it's fascism - which is plenty lawful...lawful evil.
IMO, death in a campaign should never be treated as 'cheap' - down that road lies petty excuses used to justify the 'kill them and take their stuff' mentality. I'm in the camp that says smack the paladin down, and hard - but not overtly.
For the brightest lights (like paladins), the murder in a fit of rage of a prisoner is going to leave a mark, and anything that's got the ability to see such a stain on the spirit is likely going to want to take advantage. Given the statements on what the paladin's done before in the campaign, I'd say he's a prime candidate for not a fall, but getting tripped by Evil.
