(BAD EXAMPLE, as noted by Kurd Jam) Do people do good deeds because they don't want to go to hell (if they believe in hell)?

(BAD EXAMPLE, as noted by Kurd Jam) Karma is the belief that if we do good things it will come back to us. Does that make people who believe in karma and do good things because they want the good things to come back to them selfish?

How about the people who do good things because it makes them feel better (because they did something good that day), does that make them selfish (because they're making themselves feel better)?

And when we're feeling sorry for someone and do something good to make them feel better, is it because we don't want to feel sorry for them and see them sad because that makes us sad, so we try to cheer them up because that way we can cheer ourselves up, is that selfish?

When someone is happy and they see someone who is having a rotten day, they do a good thing for that person because they want to spread their happiness so, maybe that way the happy person feels like they justified their happiness because they don't think it's fair that they're happy and someone's not. Does that make the person selfish?

Are people who do good deeds selfish?
