Thin-skinned. Sensitive. Needy. Such people need reassurance 24/7 that they're okay. One criticism can loom large and become the focus of their attention. Having multiple critics endlessly and you can see the problem the obsessed person has. Always attacking/always trying to sabotage/delegitimize/hobble. With such a mindset who has time for anything else but "getting back at and taking down"? Is that person someone with whom you'd want spend any time? Go on vacation with? Run your country? Why?
