Knowing that he couldn't stay still any longer, Christian finally started taking action. He first checked to make sure the assassin was dead, then began covering the man's neck with the blanket, or rather, his neck along with injury places, to prevent the blood from spreading further in the room.
The thought of calling the police didn't occur to him.
If things were to proceed fairly, he wouldn't have minded, as he could just claim self-defense as the reason for killing him.
But now, would they truly be fair?
He clearly didn't know this man, after all, and it was impossible for him to have some unknown grudge. Then, that leaves the possibility that this was under the order of someone else.
And thinking of the perpetrator responsible for this, someone who could order something like this, Christian didn't believe the police, when they arrived, would be fair in their judgment, based on his previous experience.
