I sometimes go there but it's not for torture porn or to laugh.
Sounds cheesy but something about watching somebody die really gives me a sense of perspective and makes me value what I've got. That pile of flesh laying on the ground was a person with thoughts and emotions a minute ago. Fragile flesh is all I am and ever will be so it gives me a sense of responsibility and appreciation for still being able to expercience things consciously rather than just not existing.
Why eat like a pig and die of a heart attack in a train like the guy in the video, or chase adrenaline by being an ass on the highway when the potential price is so high? It sounds obvious, but seeing the results really internalizes it for me.
