Good question, I understood that you intend to make him an anti hero and all that but, why have him killed to recover a simple phone... It's completely disproportionate and really stupid, it's not rainbow 6 there, it's DC, the actions have consequences. You chose for your MC the knowledge of the characters of rainbow six siege. I haven't played it much but I know there's plenty of weapons and non-lethal ways to get his phone back or whatever he's going to do next. Okay you can get him killed but don't do it for mere minions...
