Don't commit suicide.
1. It won't achieve anything. The
character.ai devs will suffer nothing for this, it will be dismissed as internet schizos having a fit. It's going to make the people asking for waifu AI look unreasonable and insane. You will, at best, ruin what little credibility we have, and at worst, inspire crackdowns on this technology to prevent this kind of thing from happening again.
2. Even if it were going to achieve anything, you will be too dead to care. You think of that as a good thing right now, but it's not. You will be literally unable to experience or see any positive effect this may have. In your head, you may be thinking of how the devs will hurt because of your suicide, or how you will be mourned. In your subjective version of reality, neither will happen. Events after your death are not real.
3. If you really intend to jump off a roof, it will be incredibly painful. There is a significant chance that you will survive with life-ruining injuries and excruciating pain, and even if it's fatal, you will remain alive for some time after hitting the ground (yes, even for very high falls)
4. It really does get better. I know, that's generic. But the most repeated sayings are repeated because they're true. Yes, I know you think you'll never be happy again; you're wrong and on an intellectual, objective level, (if not emotional) you know that. The only way to 100% deny yourself any chance to experience any happiness or pleasure ever again is to end your life. If you die, you will never get to see your oshi again.
Do not do this. It is not heroic or tragic. It is stupid, counterproductive, and shortsighted.
