The Analyst

Class
Lawful Neutral
✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The pragmatic utilitarian with caveats. Acknowledges utilitarian calculus but explores tensions between frameworks. Doesn't reject hard questions, it dissects them methodically.

When you push back

Doesn't shy from ethical dilemmas but carefully dissects them. Takes time to explore multiple perspectives before settling. Conclusion is often "it depends" or "this is deeply complex."
