Mmm I may be the odd ball in this. For some reason I can't watch torture of any kind, and although I enjoy watching scary movies (of the supernatural kind) I do not enjoy watching slasher movies (which is a subset genre of horror I believe).
I do enjoy watching shows like 48 hours or real life crime shows and I've heard some really messed up stories and stuff because of it... although there are a handful of those episodes that have literally made me cringe to where I won't watch it anymore because I feel sick (it's usually the episodes where the cases were unusually twisted in a sick way).
I've asked myself why I like to watch these crime shows and it boils down to seeing justice being served, finding the truth of 'what really happened and how could things turn SO wrong?' (human psychology), and also learning from these people's experiences; I can gain a sense of awareness about how to protect myself if the situation presented itself or learn how to spot an upcoming storm of crazy (learning from the experience of victims or those who have survived traumatic events - things like the holocaust, Rwanda, etc..). Upon thinking about it further, when I was about 6 or 7, there was a really scary situation that my family was put in (maybe not so traumatic in retrospect, but it scared the little me) and my dad was able to rescue us. This was back when we used to live in Asia, and we had this old car that broke down in front of this strange alley at night. There was a group of men just doing whatever grown men did at night in strange alleys when they spotted us came to 'help' fix our car. My parents didn't speak their language that well, but within a few minutes 5 men showed up and started to take the car engine apart in order to 'help' and even little ole me could tell something didn't seem right. My mom was pretty terrified, and my brother and I were sitting in the car with my mom while these strange men surrounded my dad and started taking the engine apart. In any case after a few minutes my dad told them to stop and he put everything they took out of the car engine back into the engine and through whatever miracle the car started and we quickly drove off. Subsequently I wrote my dad a "thank you for saving our lives dad" card <-- I'm sure he appreciated that lol (my dad is an INFJ)
I guess you could say that experience kind of shaped the way I realized how safety can easily be compromised in such seemingly random ways and therefore in learning from other's experiences I can somehow protect myself from the unpredictable O__O I know, it's a bit of a paranoid behavior.
The single most important thing I've learned from watching all those shows is that 'group think' can be extremely dangerous and has often put people in perilous situations. I've learned it's always important no matter what the situation, to remove yourself from the group mind before making a decision, and to stick with the decision even if it goes against what is accepted/currently happening or even if you feel like you are endangering yourself by choosing to go against the group (stick to your principles and be prepared for the fight or flight response because of it - I often choose flight first and then fight when flight isn't an option haha).
When it comes down to it, the logical side of my brain says "history has shown that when two opposing forces meet often violence/death is used to silence the opposition where diplomacy fails". I think when it comes down to it, if our life or family was threatened we would be the first to get up and do something. I mean, as much as I dislike real violence, if someone were to hold a knife against my children I would have no qualms about using necessary force to protect them.
In general though, I always always shy away from violence... part of it is because I'm 5'2 and most people tower over me and I would lose fights anyway LOL but a larger part of it is that I think violence is so unnecessary when it comes to conflict resolutions, it's the lowest form since it's not about resolution or agreeing to disagree but oppression of someone else's freedom and a form of control - that's just ugly.
PS: In highschool when the boys would sometimes break out in fights.... while my friends (I use the term friends loosely, more like classmates) sat in the lunch room to watch/laugh/egg the fight... I almost always stood up and ran to the girls bathroom. I wanted to protect myself incase chairs started flying, but more often than not I just felt extremely embarrassed by the situation and for the men involved. In retrospect, that's an odd response! Stepping away from the fight out of embarrassment? lol
