I got confused about the part of him returning the Blessing but there is still one striking difference and why English one rises much more questions:

English: We are a lowly mortal, unworthy of the power given to us by Hydelyn, since 'we are not gifted but chosen'. He already made his decision - we cant play a pivotal role in anything, and he is saddened he has to obey Hydelyn's wish to not kill us.

Japanese: He is in the process of making a decision. Are we worthy of the new power and can we use that power to play a large role in shaping the fate of the realm?
