That is about the first rule before helping some in trouble:
1. make sure you are safe
2. make sure victim is safe
3. order someone to get professional help (and have him/her report back)
4. attend to victim
or something along those lines anyway
Yes, and I believe that in this situation his mind was not "safe". I hope he can take this experience and turn it into something useful. The experience could be a hint, that the way he lives and treats himself isn't what's healthy for his mind and body. Aikido is not very effective from en unbalanced state.
