If we assume he is alive, very likely Kaneki encountering Arima was planned.

When meeting with Kaneki, Hide appears to have some sort of plan in mind. He apologizes for it, and we see that he repeatedly encountered Kaneki to fight with everything he had. He also scratches his cheek while talking about saving Kaneki, something (if you pay close attention) that is Hide's tell just like Kaneki touching his chin.

Meaning Hide was uncomfortable with this plan.
