actually people don't love obsessive characters. They love their journey from darkness to light , they love the transformation bec it gives them hope that's is possible to overcome the vices.
Anyways .to each their own . How they interpret is upto them. Some ppl say that showing transformation is also wrong bec in reality such ppl never change.
Ktk is an extreme show..the hero is irredeemable on all counts.
Quite possible...
What I observed from social media, I see ppl actually going gaga over such characters...
Some love the actor, hence they blindly love and defend character too...
But as you mentioned it's upto individual how they interpret it...
So yep their choice...
