Is poison use evil?

[Psyren]

As for the conundrum you posted, I've gotta run out the door, but skimming it, the "for no other litmus" is failed in the second case because you killed them because it was easier to justify as an entry killing to get into the assassins.

Right - which means you did it to get into the assassins. It thus passes the litmus and is valid. (But, makes you evil.)

My point is that the alignment requirement on the Assassin makes perfect sense with that fluff requirement in there.

As for "I killed Batman because it would impress the assassins" - that passes too. (And again, makes you evil.)
