While I don't personally think suicide is a good answer to anything, I also don't think it's my place to make judgements on those who have.
There are some pretty difficult mental illnesses out there, as well as what we've seen associated with long term concussions and hits. It's a very difficult thing many people are dealing with, and there are various reasons people in some of these situations for feeling suicide is better for them, their families, and others. It may or may not be rooted in selfishness, but either way my sympathy and empathy for them and their loved ones should overshadow any sort of condemnation. Who knows what led up to this, and when people are feeling this way it's not like they are in a good place to think things through in the best manner. They are in a high pressure, difficult life situation where it's easy to not see long term.
