Why can Heihikari be forgiven, but Dad can't?

1. In the play, the blackening of light is for revenge, which leads him to give up his identity as a country of light and choose blackening. After the blackening, it did not cause any adverse consequences to the outside world, and after the success of revenge, it continued to uphold justice and returned to the post of scientist to invent research, so it was forgiven.

2. On the other hand, the blackening of Torrekia is the overthrow of justice in the heart, resulting in a gap in the heart. The choice of blackening and being controlled by the bad guys in the play has caused great destructive consequences to mankind. After recovery, he refused to uphold justice and continued to destroy it, so he could not be forgiven.
