Hello,
Well, the idea coming out of Penance should be to ‘go and sin no more’. But sometimes satisfaction must be made. Why? Imagine if you broke someones window, go to Confession and come back. Your guilt has been removed, but the window is still broken. It is your responsibility to restore what you have taken. How would you like it if someone stole everything you had, said ‘I’m sorry’, but kept all of your goods. I imagine you wouldn’t be to keen on that.
