It's not taken from you, if everybody receives basic income, how can it be taking from you? You're missing the point.
Maybe you find those acceptable, but I find all of them horrible. Killing someone is only acceptable in self defense (in which case someone else is trying to kill you first), while cannibalism is just sick.
How is that not "depending on the circumstances"? Is not "killing is needed to defend myself" a circumstance?
"while cannibalism is just sick."
So, if someone is genuinely in a situation where their options are 1) starve to death, or 2) eat the other guy who just starved to death, you think it's clear that they should choose 1?
