Because his reason for joining Salem is petty. He decided that his twin sister (as in, the same age as him) didn't have the right to chose how to live her life because she chose a dangerous lifestyle. He then decided that rather than blaming the Grimm, or even the woman controlling the Grimm for her death, he'd blame the Headmaster of the Academy she happened to attend. And then he decided that joining said woman who controls the Grimm (the monsters that actually killed his sister) is a good idea, which directly results in more deaths of innocent people.

He may not be killing them himself, but he is an active member of the side that are resulting in the deaths of innocent people ''like his sister. ''But that's okay with him.

It's petty, and stupid. And just a really disappointing choice for his character.
