And I think the reason Future Charles and Erik wanted Past Erik out of prison and with Past Charles was so Past Charles could also try altering Erik's course away from them fighting their whole lives. Of course, doesn't change the fact that they could have just done this instead [https://www.youtube.com/watch?v=uT6YOI6JcRs&spfreload=10].
To be honest, if there's one thing I didn't like about First Class it was the fact it shouldn't have been part of the timeline as the rest of the movies in the first place, since the first X-Men movie implied that Mutants came into the public eye in the 90s and that it was only after the government started talking about what to do about the issue that Erik started taking up arms. Having it all start in the 60s and the public knowing about it in the 70s doesn't really gel that well with the other movies, though I guess it's a moot point since they've all been retconed out of existence.
