You've imagined for yourself a fantasy where your 'role' is to be the hero in that fantasy scenario you've cooked up for yourself.

And then you called attention to your fantasy and by extension, attention to yourself, by declaring 'look at me', I'm a gonna be a hero and here's how.'

That's as good a reason as any to deny you the gun.

If you're still playing role playing games in your head, you shouldn't be armed with anything  more lethal than a cap gun.
