God told Moses and Aaron to stay away from Korach and his people because he was going to bring an end to them.
“וַיִּפְּלוּ עַל-פְּנֵיהֶם, וַיֹּאמְרוּ, אֵל, אֱלֹהֵי הָרוּחֹת לְכָל-בָּשָׂר: הָאִישׁ אֶחָד יֶחֱטָא, וְעַל כָּל-הָעֵדָה תִּקְצֹף”
“And they (Moses and Aaron) fell on their faces and said, “O God, the God of the spirits of all flesh, shall one man sin, and will you be angry with all the congregation?”
Moses and Aaron knew that Korach was wrong but they wanted to mitigate the punishment for his people. They called upon the ‘God of the spirits’ that is the level that judges the actions of people. God allowed giving warning to all the other people but the people that came with Korach were already judges.
The people that followed Korach accepted his leadership and ideas and had affinity with him. Without their support he may have had a different way to express himself in front of Moses and Aaron and not coming with large supporting group.
They shared the wrongs of Korach and they shared the same outcome as their leader.
The Zohar quotes Job that went through a harsh Tikkun process. The verse below teaches us that we are judged according to our personal ways and actions.
“כִּי פֹעַל אָדָם, יְשַׁלֶּם-לוֹ; וּכְאֹרַח אִישׁ, יַמְצִאֶנּוּ”
“For the work of a man will He requite unto him, and cause every man to find according to his ways.”
Each person is responsible for his own Tikkun process. No one can blame the leaders of their community for corrupted leadership and wrong guidance. Every person needs to seek and study the spiritual system and its ways so they won’t make mistakes.
Community leaders can provide great guidance and spiritual support but at the end of the day every person is judged individually.
Study well from your rabbi, teacher, and leader but at the same time don’t follow them blindly. Respectfully ask your teacher for more information and sources to study. You will expand your knowledge and strengthen its positive value. Then you take ownership of the study and become truly responsible for your actions.
