I understood what you meant but I can't say I agree. Being faced with death and a traumatic experience like in the bad timeline creates a lot of stress. Stress that feeds off your panic and fear and makes you lash out. Orlando starts to shut down, Tyson becomes more abusive, Hoss starts swearing, and that's all because of the stress of dealing with watching a murder happen. Normal people just can't walk away from that and be fine.
I say normal as Benson and Oswin mostly have it together but there we have a doctor and his assassin butler so there is some level of ejng used to it.
