Honorius was the worst emperor in roman history, elegablus and the other people that get thrown on the worse list are saints by comparison. Honorius let the entire western empire collapse, he reigned for 30 years, so he was only in his minority for the minority of his reign. Most important, he single-handedly ruined the military situation and the city of rome by refusing the incredibly generous offer Alaric offered him, which would have been to have alarics army fight for nothing more than a generalship and supplies. That's one of the largest unforced errors in all of roman history. And he was 25 then, hardly an 8 year old. Or how he executed Stillicho, one of the best generals rome had, and caused the defection of a bunch of romes precious troops as a result.
