Why are INFPs always portrayed as good people/the good guys

The ones I know are outright bad lol. Edit: An immoral INFP tends to be one of the biggest hypocrites acting like they are morally superior to everyone and being extremely defensive/combative about everything. Think Brian Griffin from Family guy or his novel twin Holden Caulfield from Catcher in the Rye. Hell, a toxic sub reddit is the perfect example of a bad INFP.
