I don't think it's wrong to have empathy for a person even if you don't like them and they're a terrible person, which I think he is. That said I and others would be inclined to think cancer would be fitting for someone like him given the past.
While at work they sent an intern into a special room for him to rape and were shocked, SHOCKED, to find she refused to let him, to the point that all of the power of the DNC combined couldn't keep her and her family from going on the record about it. It's implied this happened often enough that it was a normalized event in his office.
He's on camera sniffing the hair and twisting the nipples of the children of the rich and powerful members of the DNC as a humiliation ritual while they are trapped, sometimes literally by their parents, so they can't escape him. Not just once or twice, but constantly, for decades. This sadistic pedophilia was so common it became a joke to the left.
His own daughter wrote in her diary in code that he was molesting her, for years. That's what "showered with daddy" means. It's "I'll be safe if dad finds this" coded language for "I got fucked in the ass by him again yesterday."
He went on camera and joked about blackmailing Zelensky to get rid of the prosecutor investigating his crackhead son, using our foreign aid money to do it, so he son could get back to selling access to the Obama white house and paying him kickbacks from the bribes he got from our own foreign aid money. This India style corruption was so unremarkable to him that it was literally a funny joke to him and his buddies.
I feel bad for Biden. No one deserves what he's going through, not even him. He deserves far worse. He's an evil pedophile serial rapist who was key at helping loot the country dry in the post Clinton era, and if you encountered him in a dark alleyway you'd be doing the world a favor if you found the nearest heavy brick and saved the ass cancer the time and effort.
