Daft Punk - Bee Is Stored In The Walls (Full Unreleased Demo)

Purity is the choice of a disciplined, mature, knowing mind and heart. It is not a thing the young can do. Even so, you are the inheritor of your past actions. Even if you choose purity and blamelessness, some will never forgive your past actions. Trust that the wise will see your pure heart.

As a rule, I do not give license for violence under any circumstances, as that license could be mis-interpreted or abused. I will say you cannot justify it, but it can be unavoidable. Trust your judgement.
