It might seem counterintuitive to want to hear someone out who has bad intentions
Like why pay attention to somebody that isn't a good person?
But there's much to learn in that too
You learn equal to, if not more, from those with traits that you don't want carried in your life
Arrogance, greed, disrespect, etc.
You learn a lot from these people. And it's that you don't want to be like them
