alignment is bad and you should feel bad

[Max_Killjoy]

That is just bad writing. And something most often found in Comics. Instead of having some plausible reason for a difficult choice you just take a villian who wants to make things difficult and you can justify any contrievances. And you have someone the audience can hate and blame for all evil outcomes.

While I don't disagree that it's usually bad writing, I've often seen this sort of scenario presented, and accepted by the audience, as a case of the protagonist being "forced or tricked into doing evil", as if it made the tricked or forced character less good or more evil for having done the thing they were forced or tricked into doing.
