God DOES work in mysterious ways! I never felt it was wrong to pray to God that He either convert of get rid of someone. If we perceive a shepherd as a wolf and in fact he is one; is it wrong to desire that God either change him back to a shepherd or expel the wolf from the flock? Maybe I should go to confession also!
Not in the least. It's not wrong to desire justice.
Blessed are they that hunger and thirst after righteousness, for they shall be filled.
