Torture Scenes in Movies ???

Lots of movie, even in the Indian movies there is a point or more than one where someone gets mercilessly beaten up or tortured. Good guy. Bad guy, good girl, bad girl.

I'm not one for violence. But in some cases u feel it can be avoided. Mostly in jails, the good guy gets tied up and beaten, or a girl gets humiliated. Although on the bright side, u tend to enjoy or motivate for it when the bad person gets their share back.

So jus wondering if these torture scenes are actually necessary
