Yes, suicide is very selfish, it haunts the people left behind. But as also said here, Junior wasn't thinking clearly so he obviously couldn't make a rational decision. I felt terrible for him, he must have been so tortured to do away with himself! He must have been in terrible emotional pain (maybe physical too) and he could have been clinically depressed. It is just a tragedy for everyone, his family, friends and fans.
I hope he is at peace with God and that his family can someday find peace with this as well.
Rejoice ever more. 1 Thessalonians 5:16
