the path should be broadening the heart instead of the vengeance, guess this angel-like being asking for Uther to revenge after is not even an angel-like being herself. when Uther said "for justice" instead of for the vengeance he should free Arthas since the justice path is not to take people's life but understanding the importance of the life, that we suffer together instead of doing it again, applying it again to some people. seems that angel-like being (she) and Uther are flawed angel-like beings, those two must not be chosen - - > > no one is chosen. so to think about the true alternative way of the story timeline since the story the video tells is just about a game, that something might be shown as flawed or just for the character plot ongoing ways or the storytelling of the plot to make it spicy although I don't prefer that 'she' at all, the course must be abandoned, Arthas will understand and know the true purpose of the paladin, or rather the justice soul together instead of just individually. (but it will never happen) when Arthas said "I see.. only darkness.. before me" meant he never saw the light, then show him the light instead of throwing him to Maw, (but still it will never happen) guess Maw will raise Arthas, Arthas arrised from Maw, or in the other way, as the next or the upcoming expansion, but soon. but since Arthas did a lot of the wrongness, he is not forgiven-able, and that only he knows himself by his saying, (by saying this it is contradict, I know) that's why, just like the normal life people. But, the people (like Arthas) will never understand, hence the throwing to Maw. (Arthas finally see the light, but the light catches him. yep it is like the police arresting the terrorists)
Edit: Still, the justice is served.
Edit 2: I was editing the post while after the writing, so you might see some weird statements which contradict the other, lol.
It's like when one (me) tries to edit but there are lots needed to claim instead, that's why
Edit 3: it is messy omegalul, will think again before the entering of the texts. (yeah plus with my replies)
