Personally i like watching violence, it's lifefuel for me, specially when it involves beating women or killing them; as for true gore i only watched out of curiosity, didn't flinch a bit due to being desensitised from a young age, some of them makes me laugh or excited, but mostly boring, because it is done to people already dead.
What about you?
I have had some interest in anatomy/injuries/forensics/medical procedures/etc. since a child. I watched material containing both sexes and read some medical/criminological papers to find the material I had interest in. Quite interesting what can be published in some papers (there was one about dismemberment in homicidies in my country and there you even saw a man with all extremities and the dick cut off - done to him by his GF).
Quite interesting are also case studies for animal envenomations or certain diseases - cytotoxic venoms produce often very disgusting results -look at envenomations from Gaboon vipers/
Bitis gabonica for example, where your tissue gets dissolved while you are still alive, they have quite large solenoglyphous fangs too - up to 4.5cm.
For comparison: King cobras/
Ophiophagus hannah with their proteroglyphous venomous apparatus only have 1.5cm, here btw some pictures of the skull; and opisthoglyphous snakes are also deadly sometimes like the Boomslang/
Dispholidus typus that makes you bleed out of every orifice and even some aglyphous snakes can kill you - like the
Rhabdophis sp. - which also accumulate toxins from their prey.
In other cases the venom was sadly overestimated - sicariids are quite the popular example for it (but they make good animals for keeping, especially the
Hexophthalma/Sicarius due to their inability to climb and due to their ability to take the colour of the soil they inhabitate). The operations look also quite interesting (like fasciotomy - where they cut open your skin to allow your swollen tissue to expand better).
And for diseases: I recommend looking at the infamous Fournier gangrene (necroses in the genital/anal region), teratomas (tumors which contain undifferentiated cells, can produce hair/teeth/eyes/etc.), gas grangene (killed many in WWI, the Nazis -especially Karl Gebhardt- experimented with it, caused by the obligate anaerobe
Clostridium perfringens, Clostridium sp. are generally based due to many extremely deadly exotoxins and also the ability to make endospores - like the more famous
Bacillus sp., which have no problem with oxygen, the
subtilis-group is btw not really all that bad, they are good modell organisms and help us to produce food, but the other groups are very deadly) and many more. Also some parasites are quite interesting (just look at
Sacculina/Leucochloridium/Ribeiroia/
Cymothoa/etc.), but for gore crotalid envenomations are simply the best. I also work(ed) with animal corpses/dissection and wanted to become a taxidermist - for me that material is extremely interesting.
