The jedi took children from their homes with force. Those children had no more families because of the jedi and while yes, killing them was horribly wrong, so was taking them in the first place.

The problem about the prophecy of the force is that the jedi were so caught up in destroying the sith to bring balance that they never considered they may be part of the problem. The only way for there to be true balance is for the jedi and sith to be mutually destroyed. That’s where Anakin brought balance. He destroyed both the jedi and sith and left the future of the force in the hands of those who know there is no difference between light side and dark side.
