It took around a half-an-hour for Sam to come to himself.
He tried his best to suppress the urges and instincts along with that feeling of him being a bloodthirsty monster that is bugging his mind constantly.
After trying his best to control, Sam became silent and sat in that same position as he closed his eyes and meditated.
He wants some peace at the moment and that moment continued for the rest of the day. He just sat there are meditated as if that is the only thing he wants to do in the world and only came out the next morning.
He finally lost that bugging feeling that is trying to take over his mind. He doesn't want to come to terms with that feeling, a feeling of being a monster. He has a feeling that once he accepted it, the rest of his life would be miserable and uncontrollable. His cold and emotionless mind which he uses to do business and create things wouldn't work like that anymore.
