If suicide is considered a cowardly act, how can euthanasia be categorised? Could you make a courageous choice?
The same scenario applies to a soldier in a war who decides to self-destruct with a bomb when the enemy approaches him and he is unable to flee; he will be killed anyhow. I recall ISIS combatants detonating themselves in combat, and the group employs suicide bombers as a weapon against anyone who disagrees with them.
