Jessie's death would've been a shocking moment had she not struck first when the wolves came knocking. She wasted no time in scrapping with the deranged female attacker, and landed a killer blow (or 20...) with her hairdressing scissors, creating a red fountain to shock the audience. It was a savage scene, but it was necessary to show that Jessie was different to the rest of the residents in the community. She quickly took Rick's harsh lessons on board and that saved her life. If she'd cowered away, she would've gone down as just another insignificant body. Instead she proved she could take a life, no matter how bloody things got.
