Without any sort of guarantee.

It’s a gamble. Literally gambling with human lives.

If one never exists, they face neither pleasure nor pain. If one is forced to exist - remember, this is never consensual - then one may experience pleasure and pain, and simply hope that pleasure is more bountiful. Hopes, dreams, goals, ideas that may or may not be met. All of it essentially left to chance. Will their life be pleasurable? Possibly. Will life be painful? Certainly. Suffering is guaranteed. Pleasure is not. Are we to keep forcing others to play, simply in the hope that things work out well for them?

No. I don’t gamble with lives. Nor should anyone.
