In Trek terms, witness the case of Dr Timicin (TNG) and the Eminians/Vendikans (TOS). In both cases their societies had developed socially dysfunctional, if not outright diseased cultures that were committing great acts of evil on the populace. Kirk (rightly) said basically "Oh no you don't!" and did something. Picard, Troi, et al just shrugged and said "it's your culture"and let him go kill himself not because he was facing a horrid, lingering death in great pain, or even because he was some sort of burden, but only because his sick culture decreed that everyone must die at 60.
Actually, I support both of these cultures to execute their respective moral codes internally
The problem becomes if it spills outside their populace and ensnares innocent people, like we see in A Taste of Armageddon
. You can't enforce your moral code on other cultures.
