You're allowed to decide where your moral responsibilities lie. I will say that "I'm not going to do anything that has no value for me personally" is a take that's caused a lot of the ills plaguing the world today. Not suggesting you have to die for others but remember that a rising tide raises all ships, and a better world will be better for everyone, including you and the people you care about.

"I'm not the one being oppressed so I'll just sit back and watch" is the stance the US tried to take in WWII until it affected them personally and just imagine how things could have turned out had they stayed that course.
