Aaron Hernandez has ZERO sympathy from former New England Patriots tight end Jermaine Wiggins -- who tells TMZ Sports he doesn't understand how people feel bad for a "psychopath" like AH.
Wiggins -- who won Super Bowl 36 with the Patriots -- is a die-hard Bostonian and still hosts a radio show in Beantown.
He's also convinced Hernandez was the scum of the Earth and lays out the reasons why.
Hernandez was found dead in his prison cell Wednesday morning.
