Here I found the remark that "The consequentialist [in ethics] is concerned with outcomes..." And only outcomes!
And thus consequentialism is no moral system at all. Because to judge actions by outcomes we already need to have some way to judge the outcomes good or bad, which implies some prior morality. (E.g., Benthamite utilitarians would argue that we should work towards the consequences that produce "the greatest good for the greatest number." But why should that be our goal? We shouldn't it be the greatest good for me I work towards, or my family, or my tribe, or the people of Uzbekhistan? Consequentialism gets us absolutely nowhere, because it can't tell us what consequences are good!)
