Then asking you to evaluate the scientific evidence appears to be too much. It’s so boring, emotionally.
Since I'm very much a logical person, I have found that the few times an emotional reaction seems to precede my logical analysis, there is always a logical reason for me to feel the way I do.
In this case, I have already read the accounts of other con men whose behaviors were nearly identical to Rossi's. So, I think the "feeling" is based on an assessment that since Rossi has demonstrated a behavior pattern, he will continue to act in a manner consistent with that pattern.
Let me guess--you would accept no evidence of Rossi's con man personality short of a psychiatric examination which, even if done, we would not see because of privacy laws.
