Is it normal i can watch snuff films with no reaction?

Just because someone's a sociopath, doesn't automatically mean they'll be a murderer. It could possibly make it more likely but, at the same time, if someone really feels no reaction to death then it may actually make them less likely to kill. If killing causes no thrill, in fact if they even consider it boring, why do it?

In a different light, couldn't someone who finds it horrifying be more likely to kill another because of the intense emotion it causes? (E.g. adrenaline junkies do things they find scary for these feelings.) Moreover, to generalise, pure sociopaths aren't really affected by other's emotionality (i.e. if someone is sad they will not feel that sadness, though they may be aware of it) and, due to this, are a lot more logical and calculating without other's emotions clouding their judgement so much. To this type of sociopath, murder is less likely because they will be fully aware of the consequences (death penalty or life imprisonment) and won't be as likely to get riled up with anger (a common motive in non-planned murders) due to the other person.

So, in reality, though it may seem someone who doesn't feel anything towards torture and etc. may seem like a potential murder, it honestly depends on many other circumstances and can - in some ways - actually make them less likely to kill others.

While I don't feel anything from these films I don't feel like doing anything I see in them. The idea of doing these things is not appealing to me.

It's not like I watch them all the time.
Most movies in general bore me. As for actual snuff films, usually people have shown them to me by sending me links or in person. I probably have a more disturbed group of friends than most people.
