While drinking I'd absolutely do things and engage in behaviours that I would never consider doing sober.
It definitely doesn't 'excuse' it. That word implies some kind of forgiveness for it. 'Explain' is slightly better, but ultimately I'm the one responsible for my actions, even when intoxicated.
I can take charge of my recovery and ensure alcohol never enters my body again. That's how I stay responsible for my actions and behaviours.
