Stop sidetracking and get back to the point at hand.
In our current state, there's no way for humans to "correct" our diets or eat substitutes so that we can avoid killing animals. You might see it as morally bad, but morally are subjective and based on a person's background and what they've learned. The objective facts of the matter are that we need meat in order to survive for as long as possible, so unless you want die young, there's no two-ways about it.
