No argument there. He gets off on the cruelty most of all when the target is someone he views as an enemy.
However, I think his dementia is making it harder and harder for him to focus on anything long enough for effective decision making of planning. His mind wanders from one moment to the next, and half the time, he can't even hold on to a single thought long enough to coherently finish a sentence. Sometimes he gets distracted by a word that reminds him of another word and he's off on some completely unrelated tangent. His ability to comprehend the "big picture" of anything is seriously compromised at this point.
In the case of releasing funds for SNAP benefits, it's possible he's purposely not acting, but I think it's also possible that he's oblivious to the whole thing. If he had any competent and responsible advisors, one of them might point out to him that he has the power to release money to fund SNAP, but the flying monkeys that are staffing his administration aren't going to do any such thing, and I'm not convinced that it would even occur to him without a reminder. I'm not convinced he even knows what SNAP is, much less comprehend the ramifications of not funding it.
I'll admit I'm somewhat biased, because I've watched a lot of videos lately analyzing his decline and pointing out how his dementia is affecting him. As a result, I'm looking at him through that lens and seeing him differently than I would otherwise. Some people look at him and still see the crafty schemer he used to be. I see a tired, weak, bumbling old coot who is still as mean as a rabid wolverine but no longer able to focus his meanness as effectively as he used to. Even when it comes to specific people who he regards as personal enemies, he simply orders Pam Bondi to go after them and lets her figure out the details.
I'm aware that not everyone sees him the way I do, but I can't unsee the videos I've watched or unknow the things I've learned from them.
