Okay, I love using this scene from Before The Storm for this card for a couple reasons, including the thematic allusions to the original card, which involves a lightning-struck tower. Not only does the scene canonically take place on a rooftop, but Kato's confidante is literally named Storm.
The scene also feels like it fits for less visual reasons: The Tower card is about sudden, painful change (and destruction) and this scene is where Kato finally stops his slow downward spiral in favor of outright nosediving as his psyche totally cracks, leading to him finally feeling forced into seeking help, and even though the end of his self-destruction is...well, the end of his self-destruction...it's also an intense, terrifying, and total destruction of the way of living he'd gotten accustomed to over his lifetime. His hitting rock-bottom and starting recovery went hand-in-hand and both felt terrifying to him...so really, I think The Tower fits the whole mess of it perfectly.
He built his unstable tower of self-hatred on the illusion that his lowest moment--or even his lowest potential moment (that of being a murderer) was all of him, all he was capable of, all that he could ever be. That he was irredeemably bad, evil to his core, cruel at heart and undeserving of anything better and only getting more because he was a cheat and a liar.
And, well. Here's the lightning bolt to tear it down. It turns out he's loved intensely, capable of and deserving of recovery, and that the man he never murdered in the first place is one of the people who would give anything for him to get help and see himself in a truer light.
