In general, Evil.
As many on this forum have pointed out, your alignment on the Good/Evil axis is less about what your intentions are and more about your willingness to perform Evil acts.
If you're willing to kill innocents, torture, steal, etc. for your cause, then regardless of what your cause is, you're Evil.

I mean, I hate to be the guy to invoke Godwin's Law, but look at Hitler - there's an argument to be made that he had good intentions. Completely insane, skewed and amoral views of "good", but he wanted the world - and especially Germany - to be a better place, with better people. Heck, he was very beneficial to those he considered worthy; he was among the first to institute mandatory paid vacations and overtime for all workers.
Unfortunately he thought the only way to do this was through genocide and slavery, and he still elected to go through with it.

Can you see why any means necessary can be considered Evil? A character like that would start looking an awful lot like Hitler, especially if he thought a certain demographic was holding the world back.
