Sexual images produce a physiological response... you get horny.
Violent images don’t really do much, maybe revulsion. But, other than that, not much at all.
A picture of a bullet-ridden corpse will not make you want to shoot people.
A picture of a naked chick having sex, on the other hand, will elicit a desire to have sex.
Apples and oranges.
To be sure, there are many who blame the ‘violence in video games’ and the like as the cause of crime. Those people are idiots... getting a good headshot in Counter-Strike gives you the exact same kind of thrill as making a basket or a hole in one ... nobody says, “Hell yeah! Now I want to kill someone!”
But, watching porn? That’s exactly what it does... the imagery itself makes you go “Hell yeah! Now I want to fuck someone!” (Which, to most porn watchers, means fucking their hand.)
If anything, a bullet-riddled corpse should evoke sadness, not the desire to shoot more bullets into it or other things.
Maybe you meant that watching one character inflict violence on another triggers audience feelings of aggression or fear, depending on which character we empathize with. What we watch undoubtedly causes all manner of emotions: horniness, elation, shame, fear, revulsion, pride, etc.
