I mean she did not avoid harm and no one forced her to, so everything is ok. She also wasn't forced to get vaccinated, she could say no just fine which means there was no authoritarian state controlling her. Decisions come with consequences. The consequence for her was a certain death in a short timeframe.

What is wrong is to make decisions and expect others to bare the consequences, like getting a rare transplant and risking it because you could get Covid and die from it because for the transplant to work your immune system needs to be held back for some time, while someone who would have done everything possible to make this work can't get a transplant.

Also there needs to be a level of trust between a doctor and a patient, so if she gets told to take specific medication or live her life in a specific way after the surgery, she will accept the advice. She was willing to take the transplant, but did not trust the doctors with the vaccine, what would she not have trusted them with?

She had her trade off and I hope she died thinking it was worth it.
