To be snatched and held in honor of the Rebbe

It is accepted in the world that those who steal are likely to be kidnapped.
Anyone who underestimates someone may be kidnapped.
This may not be something worthy, but reality shows that this is the reality, and we need to take this into account in advance.
If a certain Hasidism thinks that someone from another Hasidism has disrespected their Rebbe, and according to their style, it seems to them that it is appropriate and honorable to lynch and riot in the other Hasidism (and not in the specific person who, in their opinion, disrespected their Rebbe), is this completely condemnable?
Or is it reasonable to sneak back in?
