Why would the devil care when a soul comes to salvation? Aren't most people going to join him in the lake of fire anyway? Commentators and the like make it seem like he loses big time when a person comes to saving faith but what does he lose exactly? Obviously he can't get everyone. Does he recieve greater condemnation the more people get saved or something?
If the majority of humanity is going to the lake of fire punishment, isn't that kind of a win for Satan already?
Satan doesn't care. He is a person that is programmed without a conscience. His purpose is to seek and destroy whosoever he can, like a lion who chases a herd knows he isn't going to get all of them, just that he will eat one today. The lion doesn't regret not getting all or missing some as long as he gets a meal that day. I would imagine he suffers disappointed and hunger when he goes for days without a catch. He learns what he did wrong the last time and improves his strategy the next time. Every situation is different so he takes into account dangers, obstacles, distance, time and each prey reacts differently and has different abilities that he learns about with experience, and so it is with Satan, who is much intellegent than a lion.
But I don't think Satan is capable of having regrets for not getting one third of humanity, nor does he know his fate. Angels don't know the future, nor do demons. I am not sure about this though because he does know the Bible, what it says and works to twist and distort it. The future is in there along with what happens to him, he just doesn't believe it nor does he understand it. He does not have discernment, which requires the Holy Spirit. So the depth of spiritual understanding in the scriptures is a void to him.
It is also interesting to point out that he doesn't do anything unless he has God's permission. What? That sounds crazy but read Job. He was allowed to destroy everything in Job's life except Job.
God is sovereign and so that means He is in control of Satan and allows him do what he does. This concept is a difficult to accept but it is written into God's plan perfectly. God's perfect plan is not threatened by some rogue angel who went off and took 1/3 of the angels with him. Good and evil are woven together throughout history for the purpose of mankind to receive and learn from. His sheep are chosen out of that bunch and enlightened to the TRUTH, Jesus.

God's elect are protected, safeguared against Satan. We have guardian angels that actually do battle with the demons. We may suffer like Job but ultimately we will be saved. God does nit desire tha any would perish, there us just no other way, all cannot be saved, may will be lost.
