Moral arguments are a luxury of thinkers and only a small percentage of people can be reasoned with that way anyways. You can manipulate on morals but not reason in most cases.

Agreed that you cannot be in a toxic situation and not have it affect you -- so if THAT is the case -- by all means exit asap.

If it's perceived ethical conflict the only one you need to worry about is the golden rule -- and I do not mean 'he who has the gold makes the rules' I mean the real one. If that conflicts with what you are doing then also probably make an exit -- but many do not care trust me... They would take everything from you and feel justified as long as they are told (just told) it's the right thing. They never ask themselves. They do not really think for themselves. This is most people. Sadly.
