In some cases, yes, that's exactly what I was thinking. Although there isn't much info out there, I did find some studies that suggested there was a correlation between high protein and certain forms of aggression/anxiety/hyperactivity. Not that high protein caused these issues but that it could make worse problems that already exist. I know there are other arguments for and against a high protein diet but aggression was the one that I was concerned about.
