Yes. He's better than Keith. Keep reading. In this world Extreme Alpha's need to periodically expel their pheremones or it would accumulate in the body. They would then go crazy and act on instinct, this also causes memory problems. So extreme alphas have sex parties and frequently change partners. Unlike his brothers Greyson or Nathaniel who manifested pre puberty, Chase manifested as extreme dominant when he was older which means he has understanding of emotions and feelings which his brothers don't have. They tormented him not knowing this is abuse causing him great trauma and psychological problems. He is also not into having sex with random people and uses experimental medicine to stop his pheremones which is taking toll on his body. So he's getting crazier.
well you can blame Josh for that actually.. Chase being an alpha who marked his omega, then his omega disappears for years.. in this Overse alpha would go crazy without their omega, to add to that he didn't have sex to release his alpha urges which causes buildup over time...
Keith on the other hand is a bonafide asshole..

Y'all said that Chase is better than Keith, I am currently reading the novel and I'm at early chap.
That motherfucker is crazier than Keith he dare to almost kill(was intercepted by Josh) and he blame Josh.
There's also a part wherein he was lying in a pool? and Josh casually check if he's still alive then he almost drowns Josh.
Where the heck he is better, I'm debating if I will continue reading it.
