Parshas Korach (seen in the Mayana shel Torah)
Dasan and Aviram were not the best of characters in the desert. In fact, it seems like wherever there was trouble, those two would be there.
So why did Moshe go out of his way to call Dasan and Aviram to speak with him in an effort to create peace?
There is no chazaka by machlokes. One cannot say that these two have a reputation which precedes them, therefore nothing can help. One needs to constantly try, every little effort helps. As such Moshe once again went out of his way to go speak to Dasan and Aviram.
I’m sure I do not need to emphasize this point more than I have already. Every little bit with every type of person helps more than you know.
