Here is a serious question. Universalists believe (rightly in my view) that God will not only reconcile all people to himself but also all people to each other.
The serious issue is this: some crimes, such as the holocaust, are so absolutely horrendous that we need to be careful not to end up trivializing them by glibly declaring that God will reconcile the offender and the victims, period!
We need to say more. We need to recognize that the final reconciliation between humans does not occur by way of ignoring or downplaying the gravity of the sin or the torment inflicted. We need to make sure that our accounts do not have God riding roughshod over the wills of the victims. But we also need to affirm that whilst with humans this forgiveness may be impossible, with God all things are possible.
So - if you have thoughts on how to due justice to this issue please do offer your reflections.
