You're exactly right, but you're gonna upset the big-government nanny-state libs here. You can tell them by the way they don't care about individuals or their rights, preferences, or decisions ...they just lump together "lives" in an abstract way and proclaim that they know better than the people themselves. Oh, and if you can't do something for yourself, then you're out of luck, as far as they're concerned.
While I recognize the "obligation because of societal pressure" idea, I'm starting to question even that. We recognize a person's free will even if he's under pressure. Societal pressure doesn't mean a person must buy an iPhone. Societal pressure doesn't mean a person can't make personal decisions.
When you support death for a person who is pressured into it, that negates your claim to support that person's right to choose for themselves.
