You admit that it is one acceptable form of punishment for high treason in general according to US law?
Definition: In Article III, Section 3 of the
United States Constitution, treason is specifically limited to levying war against the U.S., or adhering to their enemies, giving them aid and comfort.

Penalty: Under U.S. Code Title 18, the penalty is
death,
[4] or not less than five years' imprisonment (with a minimum fine of $10,000, if not sentenced to death). Any person convicted of treason against the United States also forfeits the right to hold public office in the United States.

Do you admit that the citizens who want death penalty for Mr Trump if found guilty of treason is actually wanting a perfectly legally permissible punishment for that sort of crime?
So what justifies your moral outrage?
