i do not think anyone ever said it is justified or right to slap.
I'm saying people need to understand the difference between doing something out of habit and as a mistake you're genuinely sorry for.
And that is precisely the problem. As Sindhu said, a "decent" man would never make this "mistake" with his parents. Even indecent men, unless they're insane, wouldn't make this "mistake" with a boss. When they can think enough not to make this "mistake" where they could get into trouble, then slapping a wife ain't a mistake. It may be heat of the moment, but it happened because he felt it was within his rights to do so.
