Biggest lie in modern society: the outcomes of an action or the outcomes of not taking the same action are in anyway relevant to the ethics of taking that action. Examples include taxing people to feed their less fortunate neighbors or to stop a foreign genocide.

One might still do it but if taxes are theft or extortion if one prefers, one will answer for it come judgement day especially since it’s a choice one will make countless times over their life. The fact that someone else does the actual taking is also irrelevant to their culpability. Merely voting for the candidate and thinking it’s a necessity to fund the system that way, even if it is a necessity, is enough to establish moral culpability.

TLDR: however necessary an action is or however much good it does, is irrelevant to the ethics of taking that action if you violate the person or property of a third party to take it.
