I lean more towards suicide being worse.
I don’t think you could live a full life without eventually contemplating murdering someone. It comes a bit more naturally. Plus we’ve been mastering it since the beginning of time. I’m sure anyone could name a hundred reasons someone would want to kill someone else. I’m positive everyone could justify quite a few of those as well.
Suicide a little different. Our ability to think allows us to judge ourselves to an extent that actually allows us to bypass our survival instinct. Murder is simple. You just have to convince yourself that your life is worth more than the person in front of you. Suicide... especially at a young age because it is very common. You give up before you even got started. It’s like closing the only book you’ll ever read right before the climax.
