This string brings up an interesting question. The photos exhibit the typical young, vain and reckless body builder who consider themselves invincible. We lust for their bodies and joke about posting their before and after photos on this website. Clearly, we would never cross the line and commit homicide.
What if we just let them do it to themselves but accelerated the process by indulging their many weaknesses. The law says they are adults who are responsible for themselves. But, we know that there elevated levels of testosterone makes them behave like adolescents.
Say you acquainted with some of these young jocks and you have your eye on one in particular. You insert yourself into their life probably by offering some hollow admiration and a beer or two. Two of their favorite things. So long as you build upon their egos, (and buy them a beer or two) they will allow you to. (Vain people are usually to wrapped up in themselves to have real friends.) The interesting thing is that they become addicted admiration like an addict to crack. So, you just keep feeding that.
Then, you begin planting ideas like the little devil on their shoulder. Maybe, just a bit more subtle. "Look at how big that other guy is. " "I bet he takes some kind of steroid or vitamin." "Wouldn't that be something if you were as big?" That often will get right gears moving. If there is one thing a young body builder wants its to have to biggest build. You have now directed him down an alley with a DEAD end.
Another option, if you can afford it, might be to buy you friend all of the alcohol he cares to consume. He may start with beer. But, he will soon realize that liquor is quicker and less fattening. As you know, alcohol is addictive and once it reaches a certain level in the blood, toxic. Beer drinkers rarely have alcohol poisoning. But vodka drinkers often consume too much too fast. Now, all you have to do is wait for an emotionally vulnerable moment. A big win or some significant loss. You build them up if need be. You invite the guy to some place relatively isolated and you lay out the good stuff. Salt and spicy foods and lots of alcohol.
Clearly, it is his choice to overindulge himself. All you do is not interfere. (Maybe give some verbal encouragement) Depending on what type of alcohol he indulges in, he may drink himself into unconsciuousness or, preferably, cardiac infarction. Just remember these words, "I tried to get him to stop but he wouldn't listen."
Keep in mind, this is all fantasy. But, people have done it. What about you? Would you be able to carry out such a nefarious scheme? Does the means justify the end? Would you prefer to just plant the seeds and wait or would you feed it in order to speed things up?
