"Kill them" should be enough.Dominate doesn't give you immediate and complete knowledge of what the dominated person can do, does it? As in, what spells he-she has or whether he-she can cast spells at all (unless you've already seen said person cast a spell, of course).
And if you allow pointing to go along with Command. Then point and "Kill" is going to be far more powerful than intended.
