Domestic violence in the wild happens, just like shit always happens. The Lion is much bigger and stronger than that Lioness, but she seems to be driven by rage and attacking the Lion. Well, maybe that's not what's happening because none of us speaks "Lionese".
I write this with humor, even though its a serious but negligible issue when men/male suffers from Domestic violence. Women, females seems to be the only victim as the media broadcast it, many men are casualties but nothing seems to be wrong when a woman violates a man.
A friend of mine lost her life to domestic violence, the husband must be in jail by now I suppose, but the girl I knew from college days often hit guys. We were close, won't call it dating, and a couple of time she had hit me out of anger and considering my size to hers, I use to control my anger and walk away so I won't crush her bones. But from what I heard, the husband hit her one night out of annoyances and she probably lost control and hit her head leading to her demise. The husband claims despite her hutting and slapping her on several occasions, that was the first time he had responded with a bang which turned him into a murderer.
Sadly, there are many like that dude who won't fight back, who would continually endure been punched and cut with weapons like the story of Hollywood Actor Johnny Depp and former spouse Amber Heard. She looks innocent but evident later shows how she was abusing and attacking her husband.
The law seems to favor female when it comes to this, there is always this angle of Females been weaker and vulnerable to spousal abuses, but as much as Men abuse their spouse, it also happens vice versa. Its part of the fundamental faults in our existence as humans, and sadly domestic violence isn't going to be eradicated so far we humans marry and merry like the Holy Books commanded.
