I think Sawada Tsunayoshi's main goal as a protagonist is SURVIVAL, for himself and his friends.
Its so easy for them to die, protecting him or just attacked for their affiliation with the Vongola Heir. They are disposable and in the front lines of this mess.
While begin middle-schoolers and the adults are all useless (Nana) or cruel (Iemitsu).
He is scared, tired and half-way in a mental breakdown because he doesn’t want to die. Or be hurt, kidnapped, dismembered, broken...
Even Nono and Iemitsu might kill his friends to control/break him further
Tsuna was named heir and people are coming after him and his family, both Vongola mafiosi and their enemies are threats against him.
All trapping him in a role he never wanted.
Dragged kicking and screaming in the Famiglia's cold unforgiving heart.
Three adult heirs are dead (in brutal, painful ways), Mafia is a dark and unfair world, and Tsuna is stuck in the middle, a powerless 14 years old child trying to survive.
Neo Primo is his way to held on the rest of personhood they allow him, at leasts he can save other children from the same fate.
Sawada Tsunayoshi is a sealed spare heir, a acceptable sacrifice for the Famiglia, he's just collateral demaged in face of his bloodline. Not a person, never allowed to be a child.
