The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
"Not So Different" Remark when someone points out (correctly or incorrectly) that they share similar motives or beliefs to their antagonist.
In-Universe Opinion Myopia for failure to comprehend that alternate points of view exist.
Evil Cannot Comprehend Good when this is something like believing it's impossible to simply want to do something good without an ulterior motive.
At Least I Admit It when someone attempts to claim the moral high ground by owning their own ethical shortcomings.

I think that your original concept might be closest to Hannibal Lecture, actually; it's a subtrope of Break Them by Talking specifically focused on the villain giving a speech or lecture intended to psychologically break the hero down, undermine their confidence, beliefs, and sense of identity, and dig into their insecurities and failures to use against them.

Hello.
Is there a trope for the kind of villain that constantly deliver subtle The Reason You Suck Speeches to the heroes, constantly prodding and picking apart who they are and what they like and is the kind that is difficult to argue against. EDIT: Ignore this first one. Brainfart. It was Break Them by Talking. I would still need help with the second part though.
Additionally, is there something from when they go "You say you love that thing, but secretly you hate it" or some variation thereof. After all, "I hate it and there is no reason it would be different for anyone else". But if everyone say they like it, then that means I can't be the one who is mad, everyone else is. (I'm simplifying a lot here what the villain is trying to say, but hopefully I get it across)
