If the compulsion was a big one, and went back far into childhood, Gloria couldn't do anything directly about it. Sometimes it was possible to work around, and, of course, you did that when you could. The important thing was society, but you salvaged the individual wherever possible.
Where it wasn't possible—
Well, here's a man who has a compulsion to get drunk. And, when drunk, he's got to pick fights. Maybe he hasn't killed anybody in a fight yet—but some day he will. He's got the strength and, under the influence of sufficient alcohol, he's got no inhibitions about using it.
None.
You can let the man live, and by doing that kill an unknown number of other people. At the least, keeping your hands and your mind off the compulsive drinker-fighter will serve to injure others—how many others, and how badly, you can't tell.
There are times when you've got to take an individual life in your hands.
And yet, because you can't always be sure—
Gloria's "talents" could kill out of hand, she was sure. But she didn't use them that way. Instead, she simply projected a new compulsion into the mind of her subject.
The next time he got drunk and wanted to start a fight, he wanted to do something else, too.
For instance: walk along the edges of roofs.
