Is that even enough...? Will he TRULY forget his grudges in his own multi-millennium time...?
Because, even though it was said that he would experience time for several thousands of years when it is only actually one month, that's all it is.
No physical pain, and the mental "pain," if you can call it that, is just him passing time. That's all the punishment is, right?
Again, is that all? Considering what he did and all...?
