CTE doesn't make you kill other people unless you are really brain fried, in most cases you take your own life much like Junior Seau did. How in the heck did he manage to get thru UF for a few years ?
You're either joking or need to watch the documentary again.
I think Hernandez had enough internal demons to make him do what he did, Maybe the CTE had some effect maybe it did not. He did commit suicide correct?
