Depression is an angry beast and I'll never judge anyone who goes through the pits of hell fighting it. I know I have my tendencies towards depression and struggles but thankfully nothing on the level of suicide. Mental illness is not a joke and something that needs more discussion and understanding. What may seem like the "easy way" for some is the absolute last resort for others. It's terribly sad for every single person, including the person who takes their own life because they feel there is no other way.
In my opinion, suicide is the easy way out for someone who had just murdered someone or multiple people who doesn't want to face justice...that's a coward. For someone with a true mental illness, that may be the only escape they see. Selfish, maybe...but in their mind the only possible escape. That's heartbreaking.
