Suicide- Ethical?

[Coolgamer]

Should people be allowed to choose when to terminate their own lifes?
What if they are terminally ill? What if they aren't?
How is it different from choosing who to execute on Death Row? Many inmates turned out to be innocent. Was their life somehow okay to terminate, but not someone bound to die who is is constant agony?

Should people who assist others in suicide be charged with murder, even if the other person requested them to help?

How is life termination different from killing soldiers overseas or abortion?

Is it for some reason okay to kill someone againest their will, but not okay for a willing and consenting person to kill themselves?
