That's how you interpreted his story? No wonder you don't like him.
In the first game, all you were told is that he died in a plane crash, and that he didn't let his family know that the company was in bad financial shape. I gave three hints that he was still alive throughout the course of the game because bringing him back for an invasion angle was always the intention. Hint one was that they buried an empty coffin, hint two was during the conversation between the mc, his wife, and Bill where they realize she's Death. Bill says "ever since Vincent Masters has been absent from the company," and not that he was dead, which she would obviously know. The last was the setup at the end of the last episode with him sitting in the chair watching the show.
At the beginning of the second game you learn that he definitely wasn't dead, but his plane did indeed crash and he washed up on the beach of Ohana Island. The first thing he tried to do when he regained consciousness was contact his family. He couldn't because there was no phone service of any kind on the island... just a boat that comes a couple of times a year and it had just come before his crash. He wasn't on vacation... he was stranded on the island. Since this is a game and things happen for reasons, while he couldn't make a phone call, he could watch the NSFW on television every week. Just before the boat came he saw the show where his daughter became Queen of the Obscene, fucked his son, then aimed his son's dick into his son's mother, his wife, and had him cum inside of her. Believe it or not... he wasn't a fan.
He decided to not go back due to hating what he saw. Wash then found him, bitched at him, countered his issues with what was going on with his family, slapped him, then gave him an out if he ever wished to use it. Kailani and her family managed to change his mind and convince him that family was too important to lose to his hang-ups about incest. He then made his return. He didn't go back because of money and he's never once insinuated that he wants control of the company back. I know he might not be the most popular character, but he's not some Snidely Whiplash of a man, wringing his hands in the shadows, biding his time to unleash his evil plan.
All that being said... if you don't like him, you don't like him. I've reduced his screen time in the last episode or two, but he's sorta the entire focus of the wrestling story this season, so he'll be around until the end of that story, at least.
