Cause there’s also a Jewish halacha law to prevent another Jew from sinning and stop him before he sins.
There’s also a Jewish halacha law of giving mussar to your loving brother-yes of course nicely with love. The Torah says we are all responsible for one another. Hocheach tocheich es amisecha….. And if you don’t stop and prevent someone from sinning then it is on your account and the person who watched the person sin and didn’t stop him is held responsible.
So at the end of the day all yidden love one another and when they see you they can’t just walk by and say nothing but there’s even Jewish laws responsible to stop and say something or else be punished for the sinners sins.
May Hashem give you lots of Hatzlacha in all your needs.
