If you cannot disrupt a perverted culture by introducing a new culture, the politics of the perverted culture will work against you until you break, align, or leave. It is not unwise to leave before you break and it is easier to leave before you align.
I have a couple questions with your notes about politics.
Could you expand on what you mean when you say "fall back to first principals"?
"If politics thrives due to team of company culture, switch" Could you expand on this if possible?
