How do believers in hell respond to the argument "How can a finite crime (any crime we can do in this life) deserve an infinite punishment?"?

Many branches of Christianity believe that people who have done something wrong in this life will, in the afterlife, suffer an infinite punishment that is called hell. Hell is usually depicted as some kind of fire that burns souls, but souls being immortal, it lasts for eternity. Now, people who don't believe in hell often use the argument "*What finite crime deserves an infinite punishment? Even Hitler didn't cause an infinite amount of suffering, so it is unjust to punish him with an infinite amount of suffering.*". How do people who believe in hell respond to that argument?
