I know a guy who is member of Order of Malta and he actually really hates Jan Hus.
According to his words, Jan Hus was a fanatic, who knew no compromise, he not only criticized church but the king and nobility themselves, which was understandably problematic. He supposedly said to the king Venceslaus IV "see, the devil comes" and left the room.
Sigizmund also wanted to negotiate with him, but Hus did not really wanted to talk, so they killed him. You just dont want a guy with this level of influence pitting people against the king and nobility.
We, czechs have Jan Hus as a hero who died for the truth of love and compassion, but maybe there is another truth.
The problem is that I cannot find any mentions on the internet about this "other side" of Hus.
