Regarding Justin Gabriel quitting WWE, word is that he decided at the final RAW before the Royal Rumble that he was leaving. Gabriel showed up for RAW that day like usual and once again officials had nothing for him. Gabriel decided he was going to leave the arena in the middle of the day and he did, with one person saying he went sight-seeing and another person saying he went sky-diving.

Gabriel returned to the arena a few hours later and there was still nothing for him to do that night. Gabriel decided right there that he didn't want to be in WWE any more. Gabriel then booked his flight home and in between connecting flights, received a phone call from WWE Talent Relations head Mark Carrano. Carrano told Gabriel that they had booked a RAW segment for him but couldn't find him anywhere in the arena. Gabriel reportedly told Carrano that he left the building and was quitting the company.

Obviously WWE officials were not happy with the way Gabriel walked out. It took him a few days but he was finally granted his release going into Royal Rumble weekend.

Yeah it's better for him to leave. He was going nowhere in WWE.
