If you want to see how amazing Manwë's morality is, look no further than his treatment of the repenting survivors.
I don't know why this doesn't get brought up more often. It's a massive inconsistency. The Exiles who survived the wars in Middle-earth were not allowed to permanently live in Valinor. They had to build a new house on Eressea. They could visit Valinor only occasionally. Apparently, you need to die and go through Mandos in order to get permission to dwell in Valinor. It doesn't matter if you are so mighty you can convince the Valar to let a Dwarf dwell in the elvenhome, it doesn't matter if you have sacrificed so much fighting against Sauron for thousands of years, it doesn't matter how much you've humbled yourself, broke your pride and overcome the greatest temptation... The Valar won't let you reside in your birthplace. Unless if you get yourself killed, evidently.
