Barbarian

Barbarians can be a lot of fun. At early levels, your teammates wil cheer each time you rage, as you will often be the most effective melee fighter in the group. Barbarians continue to gain perks at almost every level as well.
There are two things to consider about being a Barbarian:
First, is your instinct when facing danger to bash the crap out of it? Second, is it really fun to bash the crap out of things?
While it is referred to as "rage," Barbarians are not necessarily wildly angry characters: think of it more as a a battle frenzy or possession scenario. Or, yeah, just be really pissed off, whatever works for you.
In media, Drax of Guardians of the Galaxy, The Hulk, The Bride from Kill Bil, and Wolverine are all Barbarians.
STR and CON are the most important abilities for Barbarians.

Barbarian

People of towns and cities take pride in how their civilized ways set them apart from animals, as if denying one’s own nature was a mark of superiority. To a barbarian, though, civilization is no virtue, but a sign of weakness. The strong embrace their animal nature—keen instincts, primal physicality, and ferocious rage. Barbarians are uncomfortable when hedged in by walls and crowds. They thrive in the wilds of their homelands: the tundra, jungle, or grasslands where their tribes live and hunt.
Barbarians come alive in the chaos of combat. They can enter a berserk state where rage takes over, giving them superhuman strength and resilience. A barbarian can draw on this reservoir of fury only a few times without resting, but those few rages are usually sufficient to defeat whatever threats arise.
