Oscar did not choose to be disabled!
And no, it doesn't mean that he is not paranoid about intruders. Are you suggesting that he should always sleep with his proths on in case he has to fire a gun at an intruder?
Haha you know what I mean. Just look the facts. On one hand u guys want to give him a lesser burden because he is disabled, on the other hand the very thing, his legs, which removes his feeling of disability, he specifically chose not to put on when he grabbed his gun. Can't have it both ways.
