When I am around him I will act like I have changed. Here too the young man with the evil intent lies to himself. So the young men enter business together. Good makes an agreement with bad and bad makes a deal with good. In other words I can look the other way a little if you can the other, other way a little.
Anytime good makes an agreement with bad there is a very very serious problem.
When good makes an agreement with bad good becomes slightly bad and bad becomes slightly good so to speak. Good is not all bad but good is not all good either even though good is only very very very slightly bad. G-d created the seventh day to be separated from the other six days. Separation is for every Jew and especially every rabbi, levi and kohen. Certain groups of people are easy targets to hammer on.
