This is the problem of deconstruction. If you constantly analyze and tear apart theories, you find that every abstract structure doesn’t really make sense. Deconstructing religion leads to nihilism. Deconstructing deontology leads to utilitarianism (see philosophical collapse, deconstructing utilitarianism leads to even more nihilism. This process applies to every branch of philosophy I’ve encountered, the more you think about these branches, the more you find out that every theory is ad-hoc, that every structure humans have made to organize thought are built off of nothing. In the same way that the patriarchy is a meaninglessness concept built by humans to make sense of society, maybe ethics itself is a meaninglessness concept.
