Lord Haseo said:
You don’t think he can adopt a philosophy of “Use your inner darkness to best your enemies but don’t let it envelope you for too long”? Also what’s to say that Luke didn’t take bits and pieces of philosophy that Dark Siders hold dear and use them to bolster his new philosophy?To me? No. Again, I still see the Dark Side as the malignant tumour on the energy field that life creates. It is not a difference in philosophy; it is the manifestation of the emotions behind bigotry and oppression. Being “A little dark” is akin to being “a little evil.”
We all harbor some amount of taint inside us. Luke would no doubt accept that and try to use his for the betterment of the Galaxy. The nature of these base feelings doesn’t matter so long as the outcome is good.
