The Limit of Morality

I've been thinking a lot about whether or not there is a limit to morality and I have come to the conclusion that there is, and that this limitation has to do with the human instinct. The limit of morality then become the ethical theory's lack of ability to prevail when one has to act with a sort of reflex or gut reaction due to the circumstance of one's situation. All of the theories that we studied thus far seemed to rely heavily on deliberation, which is not something that we always have the time or the necessary resources to carry out. I think that in Virtue Ethics, this limitation is somewhat surmountable because in teaching yourself to act virtuously, you increase the likelihood of your gut reaction being a virtuous one. However, in Consequentialism and Deontology, I think that this is a necessary feature because there does not seem to be ay gray area to accommodate the circumstances of one;s situation. In Consequentialism, regardless of the act or actor, the greater good must prevail. Likewise, in Deontology, the act must be good, regardless of the harm that may result. The implications of my judgment are that in order to ensure that we act in the best way possible in a ny given situation, and are therefore the best, most flourishing version of ourselves that we could possibly hope to be, we must have our morality and ethical code internalized to the extent that it because instinctual to act in an ethically an morally correct manner.
