The term euthanasia covers several situations:-
1) Killing oneself.
2) Another person killing himself.
3) You helping someone kill himself.
4) You killing someone.
5) Another person helping someone else kill himself.
6) Another person killing someone.
7) The state helping someone kill himself.
8) The state killing someone.
9) The state punishing a person for helping someone else kill himself.
10) The state punishing a person for killing someone.
Each of these situations has different moral considerations which makes euthanasia a difficult topic for me to discuss. At the moment my interests for discussion are only the situations involving the state.
I’m pragmatically absolutely opposed to the state killing someone (8), mainly because the state is clumsy, filled with incompetent, arrogant people who think they know best and they are largely immune to accountability. Likewise, the state helping someone kill himself (7) is dangerous for the same reasons. If the state were to change in character I might reconsider these positions.
It is wrong for the state to punish a person for helping someone else kill himself (9). Killing someone who reasonably wants to die is victimless except in the situation where it was likely the dead person would have changed his mind (e.g. a recently paralised person).
It is wrong for the state to punish a person for killing someone (10) if it was reasonable and truly done out of mercy. It is not on a par with murder. If done according to the dead person’s wishes then there is no victim.
Laws that punish people should be justifiable with regard to the harm done to the victim.
No victim, no injustice, no justifiable punishment.
