An a whole

What does an ASSHOLE do in his daily life:
Speaks out a very wrong sentence impulsively.
Tries to explain himself. Can not.
Feels emberrased, stuck in words.
Lost in meanings.
Gets back home feeling guilty.
First thing to do for the rest of the night:
Feeds the cats.
Who is an asshole?
Those who kill,
Or those misspeak
And feel no shame.
Don’t want to be.
And if i ever am
Please warn me.
