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

[Sacred Fool]

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.

 
I think it's interesting that in the examples people are giving, although some have good intention due to attachment of some sort, it seems to me that not so much green ray energy is happening at all.   (SP my be an exception.)  Rather, it's the scheming side of wisdom which is messing up the balance in service to the subjects' shadow sides.
  
Or am I wrong about that?

It seems to me, in general, that power-boosted wisdom is far more problematic than power-boosted love.  Statistically speaking, the latter seems rather rare, yes?

Maybe I'm just being naive?
