My take Sonny is the one solely responsible for his own death and I doubt anyone blamed anyone for Sonny's death
Whilst Carlo helped set the trap, it was indeed Sonny who made himself the easy target

After Connie's phone call, nobody could have stopped the enraged wild bull Sonny charging out not even Luca Brasi!

among others -

Godfather
  • Sollozzo to Michael in the car taking Sollozo and McCluskey to their deaths!
I hope you're not a hothead like your brother Sonny You can't talk business with him
  • Tom to Sonny just before Sonny's “Pop had Genco look what I got”
Yeah, well you're getting a great reputation! I hope you're enjoying it
  • Vito to Tom in the Fish tank scene
Santino was a bad Don, rest in peace

Godfather II
  • Sonny's daughter at Vito's surprise birthday party flashback scene
Mommy, Daddy's fighting again

Godfather III
  • Michael muttering to himself about Vincent when discussing the trouble between Vincent and Joey Zasa
Temper like his father
