Pretty much Sids a traitor who wants power and in order to gain it Satan told him to kill Cain

Cain punched the arrow out of the way that Gyeong aimed at Sid and at the same time Cain put Gyeong under a barrier~ Cain asks Sid to stop all this but Sid reveals that he took up Satan's offer of power and help to rise up the ranks in hell~ thus betraying Cain who raised Sid~ Sid then cuts up Cain and leaves~ Aaron decides to leave as well since Cain unconsciously starts sucking up their power but seeing how Gyeong is determined to stay with Cain reminds him of his past so Aaron changes his mind and decides to help~ In the end it was revealed that Sid not only betrays Cain but also is planning to take over Satan's throne~
