I'm not a religious person, so i'm not going to answer like alot of the people so far have. but i beleive people die to make life important. idk if this needs an explanation, fairly simple answer. if people didnt die, there would really be no point to live life to the fullest. since there is a limit on the amount of time we have, we do the things we want to while we still can. i try to live that way, anyway.
