Okay, so I have a dilemma. The situation is this: my MC is in a situation where he can either run for the hills and let two innocent people be murdered just for belonging to a certain group or he can stay and try to defend them, get arrested and thusly, force me to come up with a believable and appropriate escape plan to get him out of the mess his noble self-sacrificing *expletive* has got him into.
So, thoughts, people! What to do?

He has to do what’s “in character” for him. Readers feel cheated if a character does something that flies in the face of everything they’ve learned about him so far. It sounds like he has to do the right thing.
Your other option is doing away with that story element if it’s not critical to the larger work.
Okay. Thanks for the advice. 🙂
