His soul is dead. Could Christ yet revive it? That’s a question whose answer is in the secret realms that only God knows, until and unless it is revealed.
Not for me to begrudge it to happen while he is still on the earth, if it is to happen at all. A lot of us carry around the idea that Christianity is a merit system. Well it is, but it is a merit-of-God system. Not a personal-merit system. The merit that saved believers carry is vicarious, and it by necessity entails the washing away of sin, sometimes of humanly obvious great and multifarious sin.
Might he experience genuine repentance? I suppose it’s possible, but I couldn’t care less whether he does or not. He needs to die for his crimes.
He did many, many things up until that point which were basically crying out for help - including calling the authorities himself once - and they did nothing - apparently several dozen times. If they had done something, all of these lives would have been saved - including his own. It is so infuriating to think about.
I’m one of those that believes that, short of blaspheming the Holy Spirit, Christ can/will redeem any who go to Him.
