What made it wrong was the entrapment, provocateurs, planted people luring and leading people to the US Capitol building.
Donald Trump did not hold his rally at the Capitol but others encourarged gatherings around the Capitol.
FBI operatives, informants, people planted by political opponents of Trump or just crazy people?
Yes, that was wrong. But "someone convinced me to do it" is an extraordinarily crappy excuse for doing something illegal yourself. Nobody could "lure" me into smashing a window and crawling through it to enter the Capitol. Any actual Trump supporters who did that stuff are fully responsible for any of their own actions that violated the law, regardless of what others did or didn't do.
Again, any Trump supporters who were not using force, and simply were waved through by the Capitol police, have an entirely different defense.
