When has Pochita ever killed innocents to drink their blood? As fucked up as his actions might be, he still thinks of himself as a hero.
Pochita was literally begging for blood donations there, and got caught pants down by a massive attack that came out of nowhere.
At best you can say that he under-estimated Yoru and was fucking around too much. That's why they'll probably have a trilogy fight to settle the score (or Denji will do it in his stead).
