For the simple reason that he knows languages other than his mother tongue. You can see the movie “Joker” in no matter which country: you’ll find that Joker perfectly speaks the language of that country. That is to say: he has a great capacity for linguistic adaptation. That distinguishes him from other villains, who cannot compete with him since they often do not speak the language of their potential victims, and thus they end up being victimized and making a fool of themselves. In my case, without going any further, English is the only language I speak and, to top it off, I speak it with a very strong New York accent. So, no matter how villainous I am, since I cannot make myself understood in English even by English speakers, it is extremely difficult for me to do any evil, even if it is a very slight one.
