[Dirk assumed but he couldn't help but give that answer. So: the actual question.]

I know because I have to be able to 'fully conceptualize' that which I destroy. And it's almost impossible to ever fully understand another sentient being. No matter how much you know, there's more to it.

That isn't to say I couldn't kill someone with it. But the broader, more absolute sense of destruction isn't an option.

[Idly, he wonders about the one person he stands a chance of destroying. He wonders if it would let him.]
