As someone who has seen the aftermath of suicide both personally and professionally many times, i can tell you with 100% certainty that no one is ever better off without the person who ends their life.
This is not always the case, my dad was not good ever, he abused me and my mom mercilessly for 19 years, and when my mom took her car, the pets and me and left, we constantly have to live in fear of him killing us. Can't even use our names or pictures online, for fear of him tracking us down and killing us. I could never get help for my learning disabilities, or talk to a counsellour, because if they ever found out something would happen, my mom made me promise never to tell anybody. My mom was sure if we ever tried to get help, he would kill us immediately, before cops even got within a block of our house. I had a doctors appointment for acne, and at the time i had bruises around my neck from being strangled, she made me cover them up with my coat collar, and made me promise not to tell the doctor, even if he saw them, to say it happened in an accident skateboarding, because if i ever told anybody i wouldnt just be killing myself but her too, and that i don't have a right to do that.
She eventually took her car, the pets, and me and drove to another city, but we still constantly lived in fear of him, any vehicle that looked like his would cause my mom to swerve on the road.
So tell me how we would not be better off if my dad would have just killed himself, hopefully before my birth, but at any point after that.
The annoying part is that since he (hopefully) doesnt know where we live now, how will I ever know when he is finally dead? I guess it's safe to say by the time he would be 100 he'd likely be dead then, then I can go on with my life without living in fear.
