Exactly my thoughts. His heart is not in the right place, but Isami also tends to BS himself. I don't think it's just about his dick, even if he says so. They're teenagers - they're dealing with complex shit and they're trying to simplify it all, to cope better.In Defence, at least Isami is helping the families grieve better. Compared to everyone who are dealing with the guilt on their own even though his goal is morally dubious this is at least better atonement. Even though their lies, they're helpful lies. Maru is definitely the worst out of all of em I can see it.
