CMV: You can be a kind and mentally healthy person and still get off to fantasies of torture and murder.

There seems to be a common trend of sensationalizing what people enjoy or find thrilling in their private thoughts as being dangerous if it does not fit into the narrative of what others deem normal or acceptable. People seem to believe that your thoughts influence your actions so much that you couldn’t possibly just enjoy a harmless fantasy for your own pleasure without it being who you are at your core.
Well, I disagree. You can be a kind, empathic person in reality who would never hurt a fly, but get off on the thought of torturing someone to death in the private fantasy world in your head. You know in reality it would be sickening and wrong to do such a thing, but in your mind, it is a fun indulgence where you get to be as cruel and heartless as you desire. This doesn’t mean you are at all influenced in your daily life by these thoughts.

You see the same kind of overreaction from people when anyone gains any kind of pleasure from something considered taboo. People call it “normalizing” and “sick” and don’t even think people can enjoy fictional stories or drawings depicting such things. But people fail to realize that fantasy is never the same as reality and humans are into a lot of shit they would never do. That’s why roleplay exists in the first place.

Where does the enjoyment in torture fantasies stem from?

>You know in reality it would be sickening and wrong to do such a thing, but in your mind, it is a fun indulgence

I think the thing is, we don't act based on what we think is acceptable. Our behavior is a response to what we feel. If a feeling is strong enough, we will act on it regardless of whether we think it is acceptable. 

So if you have fantasies of torturing and murdering people, that means that you would enjoy it. If you incubate those feelings in fantasy, they could overpower your will to stop them playing out in real life.
