I struggled with this while in graduate school studying neuroscience. Fortunately, I was studying crustaceans so there were not too many ethical issues. But there was rodent and monkey research happening in the school. I choose to return to my first profession - software. I assume that I'll be long dead before there are ethical issues with experimenting on AI. Animal research is something that we as a society are going to struggle with for many years into the future. I would like to be able to argue that it is for the greater good of the planet, but I don't think that I could put up a good argument that we are being proper stewards of the planet.
