Cecil really could of handled Mark’s concerns better

Mark was obviously emotional about the use of Sinclair especially what he did to his friend. Instead of having a rational conversation with him and showing his own past views surrounding it or even just letting him blow off steam, he antagonises him and immediately starts exploiting his biggest weakness. Like wtf did he expect Mark to do after doing that? “Oh yeah Cecil after you planted a weapon in my head, sent robot zombies after me and force me to stay I think I see your point of view now”. He is literally the strongest man on the planet and he didn’t expect him to retaliate? If anything Mark under reacted. Cecil of all people should really of know how to communicate. Also I’m only halfway through episode two so I could be missing something monumental.
