Is Aldon a much better person than Hardy?
From the descriptions of the incidents, yes; if "better" is on a continuum of violence, it sounds like Aldon was less violent with his partner than Hardy. I wouldn't want Aldon throwing me around a room but I'd prefer it to Hardy choking me out and threatening to kill me. You can say both are bad without playing dumb and pretending they are the same.
Smith's domestic violence incident was in 2018 and was bizarre. Biting someone on the wrists really isn't what people imagine when you talk about domestic violence; it's striking a partner. Obviously, throwing someone around a home is awful.
Hardy, on the other hand, left his partner bruised from head to toe after throwing her around, "choking her and threatening her life."
