Depends on to what degree. You have to have your own needs met before you can help anyone else, so you have to be selfish and/or greedy in order to meet your needs and to insure survival. After that... well there are people who are selfish to a point you want to just kick them to the moon without a return and there are people that are so selfless you can just shake your head and say "There's no way I could/would do that. ". I would consider myself somewhere in the middle. I donate my stuff I don't want anymore instead of throwing it away even though that would be more convenient, cause I think someone else would definitely benefit from this stuff. However, one can reason that even this is selfish, cause it makes you feel good to do so (not so sure if I would agree with that reasoning though). Anyway... anything is bad if you overdo it... mho
