no literally every protagonist is the good guy thats what protagonist means.

Except that's not what protagonist means. The main character is the protagonist and their opposition is the antagonist, regardless of alignment.

Edit from wiki: The term protagonist comes from Ancient Greek πρωταγωνιστής (prōtagōnistḗs) 'actor who plays the chief or first part', combined of πρῶτος (prôtos, 'first') and ἀγωνιστής (agōnistḗs, 'actor, competitor'), which stems from ἀγών (agṓn, 'contest') via ἀγωνίζομαι (agōnízomai, 'I contend for a prize').

Double edit: I completely missed the sarcasm my bad
