You're in trouble if you expect lawyers to be any more soft-hearted or non-judgmental people than anyone else. You can, occasionally, expect lawyers to be manning the barricades to defend liberty, the rule of law, individual rights, etc. We're not, as a group, especially well-suited to being avatars of compassion and and acceptance. That's what kid-toucher clergy are for.
Some of the most dedicated and effective lawyers doing genuine humanitarian work are total megalomaniac assholes. Loving humanity, not liking most humans, or however that saying goes. And sometimes I think it's not even humanity such people love so much as the fight. The Myth of Sisyphus and all that.
I know lots of public defender types who are pretty damn cynical and contemptuous of humanity in general and their clients in particular. They believe in the Constitution and delivering nut-kicks to the Man, not in the innocence of their clients. As a rule, I think they tend to be much more effective advocates than the pathological true believers.
