“Do you think there is absolutely no correlation between Torah learning and middos and/or ruchniyus (spirituality)?”
There is no connection between middos and being an inherently better person.
I know a man who had great middos his entire life, but now when he is very old in his 90’s he cant learn anymore and he lost his filter and is kind of rude and blunt with people- saying whatever comes to his mind. He often hurts people’s feelings. But most people dont take it personal because he is very old and thats how old people often are. But he is usually very caring.
Is he a worse person now that hes old and more blunt now than he was 20 years ago?
