I can’t go into too many details to avoid doxxing but I know someone who was doing a biology PhD at a major university and they were supposed to do testing on a certain amimal for their thesis.

But they became emotionally overcome by how cruel it was, so they stopped testing on the animals. Instead they hid the animals and cared for them kinda like pets for a long time, given how much leeway is given to PhDs no one really noticed that no actual work was even being done. Once it came to light, they got into a lot of trouble and eventually had to leave without completing their PhD but had some arrangement where they were excused due to having some emotional disturbances.

Honestly, deep respect for the personal hit on that one.
