Corrected entry: It seems ridiculous that Raven acts selfish saying Charles never sacrificed to save anyone. Clearly, and I speak for others not just myself, she was there to see him get crippled saving both the whole team as well as the USA and USSR naval vessels in X-Men: First Class.

Correction: That's not a movie mistake, it's the character's opinion. It's insensitive, but her point was that they have friends that have died for the mutant cause. She is annoyed that Charles continually will send his team out on dangerous missions while keeping himself out of harms way. Her opinion might harsh but she certainly has a point.
