It is true that one can regret being born, to find that the time one has lived is already too much.
But if a painless right to suicide is at hand, then you can erase everything right away, including memory. Because when I die, there is nothing left, so no more memory either. NOTHINGNESS.
I also think that life has its joys if we can taste them. But this is of course not a reason to condemn someone to live. Life is sometimes a chance, but never a duty.
Sorry, I meant our memory that lives on in others. And our time in suffering in this world, it really can't be erased, it can only be ended and our consciousness of it, put to sleep forever.
Kind of like shutting down a computer or even smashing it and tossing it in the bin. You can break it down but you can never truly erase it. Once something existed, it can never not have existed. The pain and lack of joy that happened will never have not happened. And the existence that someone regretted to the point of suicide will continue to be revived in the minds of others, long past the person's decision to take their lives. We just can't have control of things once we are dead, not even the memory the world has of us.
This can be good for those who appreciated their existence and instilled a pleasant or worthwhile memory in others. But it is yet another detriment to those who regretted having been put into existence and were not able to live a life they wanted ingrained into the minds of everyone else who continued on after them.
Imagine your most painful, embarrassing memory. Imagine that being your whole life and the only thing everyone knew about you. Imagine dying to end the pain but your terrible experience outliving you in the memory of other people. That experience being what you were and what you will always have been. Even if you are dead and cannot realize it.
I hope that better underlines where I was coming from.
