What does "The Road to Hell is Paved with Good Intentions" mean?

[zedro]

It means that sometimes people who think they are doing the right thing are too ignorant to fully understand the consequences of their actions, and lead everyone down a perilous path. In LOO terms, it's a severe imbalance of love over wisdom, where the wisdom is next to non-existent, at least in the long view.

Its my favorite saying, because I see it everywhere, especially in government and activist actions, or any relationships that involve a custodial power dynamic
