What If?

What if things were different after Voldemort's presumed death? If Lucius went to Azkaban? If Sirius had died after killing Pettigrew? If some Death Eaters escaped imprisonment? If Dumbledore didn't know about Horcruxes? If Dumbledore actually had to explain things to people and not just have them blindly obey him? The possibilities are endless. Lots of bashing
