Hi, I'm guessing it's more of a tradition than anything else. Remember, the Don refused to grant the Undertaker's request to have his daughter's attacker's killed, because she was still alive and that was not justice. They compromised that the Don would arrange to have them "suffer", like she did. Also, note the comparison to opening scenes of GF 2, where Michael was granting audiences the day of his son's First Communion celebration.
A wise and frugal government, which shall leave men free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned - this is the sum of good government.
