Pride didn't hold back on his back attack. The impact was so powerful that Hope lost control over the confinement barrier he trapped Fear and Wrath in. The barrier vanished. Fear and Wrath lunged forward once they did.
Wrath sent a torrent of chaotic energies at the two goddesses from the opposite team. Serenity and Love had been taken by surprise. They didn't expect things would turn out like this and they didn't know what to make of the fact that Pride was backstabbing their leader. All they could respond with was defend themselves when Wrath's chaotic energy came assailing.
Pride didn't stop after that one attack. He continued to unleash one catastrophic energy after another. He was trying to keep Hope from taking any action.
"Enough…!!!" Hope bellowed. His voice created a shockwave that would have shattered mountains.
