Is suicide a selfish act, a courageous act or morally neutral?

Or does it depend on circumstances? If one kills themselves in the service of a cause is it courageous if you believe in the cause and stupid if you violently disagree? Does it depend on whether or not you left loved ones or duties behind? If you are terminally ill and don’t wish to endure more suffering?

Do we have the right to judge?

These questions fortunately don’t arise out of anything personal. Just some musings after a discussion with a Jelly-friend. Thought it might make a good discussion topic.
