Should Daniel's mom have locked him?
That guy is a danger to society, an environmental hazard, worse than a leaking canister of Plutonium. Watch and see for yourself (and have a good laugh):

He wouldn't simply open a gate: he HAS to kick open it while giving a battle cry, and does not care if there are people on the other side. And that's only the beginning: everything he gets in touch with - he ruins, and doesn't even care if someone gets hurt as a result (like the people in the three damaged cars).
What do you think: should his mom have kept him locked in his room, for good?
