Is euthanasia right or wrong in your opinion?

Definition of euthanasia : The painless killing of someone dying from a painful disease.
I need some opinions on whether you think this is okay or not. I know some religions strictly forbid it but I still wanted to know some personal views on this. Do you think it is wrong or right?
Here are some types of euthanasia and don’t worry jellies, this has nothing to do with my personal life:
Voluntary euthanasia: Ending life painlessly when someone in great pain asks for death.
Non-Voluntary euthanasia: Ending someone’s life painlessly when they are unable to ask, but you have good reason to think they would want you to do so.
Thank you.
