Doubter

The immature doubter would be a cynic and nihilist type who has no trust or connection to the moment. No ability to do anything other than to compulsively doubt and rely on past conditioning and wounding.
The mature doubter plays a healthy role as an empiricist, bullshit detector etc... It waits and observes rather than being compulsive.
If you go even futher, the mature do it doubter is close to the void or the witness itself, as it buys into nothing and lets everything pass on its eay.
Even there you have a spectrum from hell <----> human <---> divine
But it's best to experiment for yourself and see what shows up.
