Right that is the utility-maximizing moral view. The other is that all you can control is what you do yourself. If the other 1000 will die, but not at your hand and not by your free will (implicitly yes but not explicitly), one could contend that it is still morally wrong to kill the 999 people.
I should have specified that the 1,000 will be killed by another man who is giving you the choice to personally kill the innocents to protect the group. It is not a choice of you personally killing one group or the other.
