Charge them with the felony, absolutely. My point is that the fact the guy killed himself should have no bearing on the punishment. How many people in this same situation would have chosen to kill themselves over it??? I suspect that number would be extremely low.
How many people die from being shot with a pellet gun? I suspect the number would be extremely low. Nevertheless, the one poor schlub that takes it in the eye socket and into the brainpan is just as dead.
Just because something that is done intentionally to victimize somebody does not usually lead to death does not exculpate the responsible parties when it does.
The case of the Missouri girl who was bullied on facebook, and killed herself, the Irish girl, there are many examples of stuff like this causing someone to kill themself
