No, you "shouldn't" feel vindictive. Vengeance doesn't really help anybody. We are all wronged, and we all wrong others. None of us is perfect.

Some are worse than others, and we have laws, and punishments, etc.

But I believe there is no morality to seeking pain in others; even if you believe they deserve it. It will not raise you up, so to speak.
