Simon is a ruthless mercenary who is willing to kill people for money. He seemed to take great pride in his work as he even tracked down one of his surviving targets to the hospital to finish him off. He mentioned he did not kill Sara Lance and admitted he would have said it if he had as he is proud of his work. Despite seemingly killing without qualms he only killed targets he got paid for.
