I would never begrudge someone with a terminal degenerative illness choosing the manner of their exit.

And there are states of mind which, had you ever experienced them, would have you pleading for a swift end to things. You are lucky to have never known them.

Good and evil don't necessarily come into it at all, except for in a judgmental observer's mind. Some people call abortions evil (even if they're terminal, or a result of rape, etc). Yet they feel different when it's their abortion.

Many people felt gay marriage was so evil that it would end society as we know it. Same with cannabis; same with left handedness.

Sometimes suicide is a permanent solution to a temporary problem; sometimes it's a mercy. What qualifies you to judge someone else's decision and label them evil, without so much as having met them?
