Two times in the late 80's and early 90's I was unemployed and looking for work and turned down good paying jobs cause the work grossed me out. One was as the EH&S manager at a rendering plant. That was funny. They interviewed me then offered me the job. I said "Let me think about it." I called them back the next day and declined. They called me back the next day and offered me more money. I declined again. They called me back a week later and offered me even more money. I declined. They were astounded and told me they were offering me nearl double for that position then what they had ever paid before. I told the guy. "Honestly, I just couldn't work there. It's to gross".
The other job was at a Pathology lab that did required animal testing under TSCA new product regulations. I did the interview and was offered the job and the video you posted pretty much describes why I turned the job down. On an emotional level, I just couldn't do that.
