[DC,batman] What would happen if Mr.Freeze could save his wife, would he go back to being a regular guy? Or has he already gone to far?

In an ideal world, he would use the cure he developed to rid the word of cancer, and then turn his genius to to heart disease or diabetes or whatever he thought was most likely to take his wife again, a few years down the road.

But Freeze has already shown that he isn't exactly playing with a full cart of apples, so the most likely result is that he becomes obsessive about protecting her. This would probably be a combination of "typical" abusive relationship behavior - controlling her schedule, limiting contact with friends and family - and more super-villain behavior like building automated ice weapons to flash-freeze anyone that tries to break in during the night and murder her.
