I think the words you’re looking for are mouring or maybe lamenting. There aint no struggle killing zombies. I really dont care to debate the point with you any more so have a good one.
No the word is struggling. Andrea refused to put the second kill on her sister until she could look her in the eyes and not see her sister anymore, she even said as much. There’s no other word for that than struggling.
“ain’t no struggle killing zombies”
On top of those situations already mentioned I recall Rick saying that upon seeing a zombie for the first time his instinct wasn’t to kill it. He had to learn what a threat they were, and he’s among the most aware and capable characters on the show.
