Man! What a complicated song!

I've been reading through the lyrics and have come to the conclusion that the main character of the song is a student/trainee and the other person is the mentor/teacher/trainer. After the mentor taught him all he needed to know, he left him alone as he should be. The mentors job was done.

However, there are lines about the mentor hating him. I believe this to be the blood sweat and tears that the student shed while under the teaching of the mentor. The student can become frustrated when It becomes difficult to match the physical or mental torture he must endure to achieve victory so he questions the mentors knowledge. This leads to conflict between the two people. (Which is kinda why the mentor hates him) The reason that the hate only comes from the mentor is because the student now realizes, after victory that the mentor was right all along. The student now desperately tries to apologize and seek out forgiveness for taking advantage of the mentor.

But it is too late, the mentor knows the student just used him for his own gain. And felt the student would just throw him to the side when he achieved victory, so the mentor left.

The mentor changed the students life for better and for worse.
