I don't want any hard feelings here but how could it be anything else? What are you accomplishing?I can understand why you and some may feel this way but I personally disagree about it being selfish and cowardly.
I can understand in extreme situations butt for the most part it is a dead giveaway that you lack fortitude. A difficult life is much harder to deal with than 10 minutes of physical suffering so aren't you taking the easy way out when you forfeit any possible tomorrow because you just can't deal with right now?
I mean, what I find disgusting is treating these people like they died of a tragedy they could not control. No. They died because they chose to do that. Making them a victim of anything other than their own selfishness and cowardice doesn't help anyone.
