The character that I$\text{'}$m choosing from the Case of the Killer Robot is Jan Anderson, who was the former programmer and analyst at Silicon Techtronics who opposed the use of the waterfall model on the robot project and as a result, got fired for speaking up$.$ The firing of Jan reflects the failure on behalf of Silicon Techtronics' management to value work place ethics and the well being of their employees. They refused to consider Jan's feedback and working to find a better solution, they chose to silence her, displaying how a lot of companies sometimes prioritize profit over ethical concerns. According to the ACM codes of ethics $($Principle $1\mathrm{.}5),$ computing professionals have a responsibility to "respect the privacy of others" and to "take responsibility for their work."

Jan's ethical responsibility was to speak up when she believed the project was being managed poorly, and it was Silicon Techtronics' responsibility to respect her professional opinion. Instead, the company violated her rights by firing her for trying to improve the project, which could have helped prevent the tragedy from happening. An ethical theory I would apply to Jan would be Utilitarianism because it prioritizes the greater good and the greater good would have been served if her warnings had been addressed. This failure in leadership ultimately resulted in harm.
