Can any vampire or supernatural creature decide how much they want to turn off their humanity?
Elena had completely turned off her humanity and so she started killling and rudely commenting on her own friends too
Vampires like Klaus and Katherine are mean and very ruthless but they do not seem to have completely turned off their humanity.....they still feel and care about their loved ones
So i want to know that has Klaus and Katheirne turned off their humanity or they just simply pretend to not care or show their weakness to others
In the series they have never been able to only turn it off partially it seems to be all or nothing.
We see it in Damon when he has to walk away from Enzo, Elena when she sets fire to her house and kills, Stefan when Klaus compels him to turn it off. It all goes. there isn't a halfway switch.
When it comes to Klaus and Kat, they still have the ability to feel and have their own inner struggle but they have been so focused on either surviving or being on top for so long they choose now to bury it or ignore it.
Klaus has shown great capability to feel when it came to Caroline in TVD. He showed he wanted to share his love of art and beauty all around the world with her, to appreciate her honesty. As he longs for a person to share all his wonders with, although then he worries too much that that would mean someone else would have something he wanted and so he goes back to plotting and manipulating and is willing to sacrifice most things to get whatever he wants.
Kat has felt hard done by all the time, she showed us a glimmer of her humanity when we saw her loosing her baby and her hope to find her. Then in her hope for love and her courage to run and kill herself to stop Klaus. She survives. That was her gift and her curse. She was embracing her humanity when she came back for her daughters last moments, but was regretting that her own need for survival was the reason they didn't get to Klaus blood in time. She had plenty of times with Elijah that she showed love and care and he wished that she would be more like the Kat she was when she was human but even he had to walk away.
They haven't turned it off, they just have desires and ambitions that obscure and override them. They see it as a potential weakness and they have to be cold and calculating to pull off their plans which is why they were always ahead of the game.
I think it's not a matter of turn on or off, that's deliberately done so people who only see in black and white can understand, at least I hope that's the reason.
Regarding Klaus, Katherine and Damon I would argue they all have lived long enough due to their circumstances that they have started to lose their humanity over time, I mean if you are a vampire and has a need to kill and feed and then a couple of centuries passes and you still do it, it becomes more than your nature. I would also argue that there's psychological effect both based upon how you were as a human and then the early years as a vampire.
We know that Klaus was abused by his father and his mother ignored him (and from his perspective his siblings didn't help either) along with the fact he felt responsible because of Esther's affair when his father blamed him. Throw in that he was born a werewolf and with that comes aggression, likely magnified when he became a vampire.
Katherine never got to hold her daughter and lost her family way too young. Out of context in the show we can likely assume that up until she met Emily in 1864 or some few years earlier so she spent some 380 years on the run from Klaus with no daylight ring and no friends except Pearl (but we don't know how early they met, it's disappointing they never revealed that).
Damon was shunned by his father and while Stefan did seem to be want to be on his side he didn't actively defend him when his father insulted Damon for not being a prideful son combined with losing their mother too young (see Rebekah situation). He also didn't have Lexi, Katherine taught him how to be a vampire along with Sage educated him to "enjoy" it too.
Yeah, it's fully off or on. The thing with Katherine is when Elena had her humanity off, she said "Atleast I deal with the bad things I've done instead of turning my humanity off." Klaus and Katherine have their humanity on, just they hide their emotions to make them seem stronger.
What do you think?
