Definitely the sexiest thing about Harvey Dent across Batman continuities is when, y'know shortly after losing half his face, he starts working his way through the Gotham underworld and you can very quickly tell that this isn't what you'd call a rampage. 'Rampage' implies he's acting pretty much purely on impulse, but no, he sits down with various mob goons, maybe goes apeshit on a few of them, does his coin flip, et cetera, but the whole time, you can tell, he has thought about this for years. He's figured out all the gang hierarchies, he knows all the hangouts, he knows exactly where the gaps in his knowledge are and whose ass he has to kick to fill them, and he's working his way through it like a grocery list. And it's clear that for years the law was the only thing holding him back from doing this and now it's not holding him back anymore. It's equal parts terrifying and satisfying and anyway that breach of the line of law and the childhood friend thing is absolutely why he's actually Batman's greatest Rogue. Because Batman has also thought like, way way, way too much about what he would do if he didn't have his code. Do you see the vision here???
