Kabbalah zu Schemot 21:33

Rabbi Itzchak and Rabbi Yehuda were going from Usha to Lod. Rabbi Yehuda (Yitzchak) said: let's say some words of Torah and then go. Rabbi Yehuda (other versions Yitzchak) opened with the verse: " When a person opens a pit, or digs a pit etc" (Exodus 21:33). What is written after it? "the one responsible for the pit must pay etc". And if this is so in this case, to those who bring evil in the world through their transgressions all the more! I am astounded by this - they brought evil into the world, why is there teshuvah for them, as it is written "man or woman, when they do evil etc" (Numbers 5:6) "they shall confess the wrong and return etc" (Numbers 5:7)
