It has gotten much worse since i removed the angels and tetras. I think the angels were keeping him in check lol.
That is a possibility in a round-about way. Other fish in the tank will obviously distract the barbs somewhat. But this is not a viable solution, because the barbs will overcome that and show their normal behaviours, as this one has done. They are the way they were made.
One caution, if you intend getting more barbs. The nasty one now might be a terror with even more. Once this aggressive behaviour sets in, when caused by stress as it was here, it is not reversible. If the store will do it, it would be good to return the two barb you have and buy 8 not including these two. Explain to the store that this is your attempt to avoid the increased aggression of the fish. If they want your continued business, they should understand.
