Quotes I've found over the years that spell it out nicely
Since we can't all be saints, let us be sinners. The best way to imitate God is to cross every boundary, transgress every taboo, and mix (as God does) the sacred with the profane. Orgies, incest, rape and sexual intercourse with children including sodomy on young boys is no longer sinful and should be practiced liberally.
The reason they behave in this manner is because they believe all things, evil and good stem from God. The world has to enter into absolute good or absolute evil for the messiah to come. They don't believe the world is capable of behaving in an absolutely good way, so they want to provoke the world into behaving in an absolutely evil way. This will provoke God to bring down the messiah and bring on the messianic era. These kabbalaistic Jews believe that they are duty bound to make the world an evil place to destroy it, making God come and create a new good world.
The Sabbatean-Frankists subscribed to ''Redemption through sin'' as their motto, that's why there is so much moral decay in society. You ready for this redpill? Kabbalists believe that God is ‘dead,’ and it is their duty to ‘repair’ Him (tikkun olam) by reintegrating the dark into the light. They do this by destroying the barriers that separate light from dark, i.e., our moral boundaries, so as to mix the two together, whereby they believe they can return the darkness into its holy place as a part of the infinite God. So, sin becomes an act of righteousness, and there we get the inversion of God’s Law. They believe that the personal God of the Bible who gave the Law is only half of the “true God” and that the Law was meant to maintain the separation (which, it is, but not for the reasons they think). The jewish foundational myth is centred upon the idea that the tribe of Israel was founded by a disparate group of people in a time of turmoil. The essence of Kabbalah is that all people must be brought together, in essence "healing the world" through the practice of Tikkun Olam.
