Mrs. Hutchinson really wanted to stop being trapped in a world where she couldn't change anything, where the Lottery was something as natural as day or night, and she was already tired of being a woman who always struggled to fit into that society. She didn't want to follow the rules, but she was a rebellious person inside, and perhaps for her the only way to escape was to die. Although she seems abnegated and peaceful, she actually thinks that the Lottery is unfair and even its late the Lotttery's day. Tess Hutchinson wants to end all that, even dying. It is also logical to think that she succeeded.
