I'm not sugar coating this sucker: This is evil. This is the evil outcome of evil human will on the part of six human beings to pleasure themselves with those who cannot defend or speak for themselves. If the charges are proven true beyond a doubt, these men need to be taken away, and kept away from the community at large for the course of their natural lives.
No one is beyond God's forgiveness, but society cannot give any mercy here. They must rot in jail for the rest of their lives. Period.
