"What are you trying to do, you bastard?!" The soul shouts at Reign who uses his ability in order to slowly corrode the connection that the leader and the base had. The chaos energy had already done a lot of damage to the thread that connected the two, and Reign only need to slowly integrate his own soul with the core before attempting to get it to connect to him and not the leader.
He was tempting the core, showing that the connection it had with the leader was not a good one and that it was only a matter of time before it would get destroyed. With the leader being incredibly weak now, there was little he could do, and thankfully for Reign and the others the leader did not in fact remember anything nor did it have a single tactic it could employ in order to stop Reign.
