Aside from the point, my support for judicial executions due to treason against the United States is not support for extrajudicial executions, like the ones that ICE has been carrying out. I think Italy and Romania are decent examples of countries becoming better off after executing their authoritarian figureheads, although I don’t think that there are grounds for that in the United States yet.
Execution != assassination, as the latter has a lot less success in creating real, long-lasting change than the former.
