NFL's Robert Nkemdiche -- Laremy Tunsil Hacker Is 'Evil'

The person who hacked Laremy Tunsil right before the NFL Draft -- and posted video of the football player hitting a gas mask bong -- is pure evil ... so says Laremy's ex-teammate Robert Nkemdiche.

Nkemdiche -- the 29th pick in the NFL Draft -- played with Tunsil at Ole Miss ... and was IN THE ROOM with the lineman when the video came out ... so, we had to ask his thoughts.

"That's wild dude ... that's evil, whoever did that."

We also asked if he thought Laremy's stepfather was involved -- since the two have been feuding over an alleged domestic violence incident since last year. For the record, Laremy's stepfather has denied any involvement.

Still, Nkemdiche had some advice for his friend -- "Laremy, brush it off dog ... I love you. I don't care about all that."

Later that night, Nkemdiche was spreading the love ... giving money to a homeless guy he befriended on the street. Cool video.
