Shavua Tov. There is a concept in the Gemara called מידת סדום, a measure of Sodom. This refers to a situation where one objects to prevent someone from doing something that doesn’t affect him in the least.
He only gets in the way of another person’s activities out of cruelty. If he can’t have this benefit, why should the other guy have it.
This is learned from Pirkei Avot where the Mishna describes one who simply says שלי שלי ושלך שלך, what’s mine is mine and what’s yours is yours. Some say this is מידת סדום , because such a person will never give anything of himself to another person.
As Jews, we are taught to be giving and caring, and go beyond the letter of the law. There is no place for מידת סדום in the interaction among Jews.
