To answer the question, no suicide is not wrong, especially if you are terminally ill, there is no good argument for keeping terminal people alive to suffer more. However, my philosophy on suicide is that, in a way, we all commit suicide. Whether you outright end your life or you live a healthy life and die old, that's still choosing your own death to an extent. Whether it's old age, organ failure etc. You could even look at smoking cigarettes as a form of suicide, or eating unhealthy food constantly, or taking many prescription pills every day. I would go a step even further and say I would not blame any adult for taking their own life even if they just didn't want to live anymore, even though ideally I want everyone to live healthily for hundreds+ of years.
If the hypothetical idea of an afterlife means more to you than the objectively true reality we all share, then you deserve no respect.
