Actual real physical threats against your family sober you up and focus you. Yes, that will wake someone up.

I would contend that the majority of people have the opposite reaction. They withdrawal, they appease, and they blow smoke and sunshine up the aggressor’s arses. Their focus does not sharpen, but in fact it suppresses in a state of denial and fear. I am impressed with Tucker, although he did have conduit already in place with which he could use to channel his justice.
They retreat in fear, especially if they don't have the resources to protect themselves and fight back, yes that's normal.
