Not yet to the level of it being sentient. Yeah, it just affected Ben, making him crave and when transforming, he transform to Bigchill and becomes somewhat like a predator wanting his prey except BigChill just wants to reproduce. He is still Ben except and he was affected as well and when transformed Bigchill's form takes over his consciousness so he can reproduce.

We all have our subconscious don't we, like sometimes we tend to do things but do not remember doing it, or we tend to do things that we never wanted to do in the first place.

Like when you feel ominous of something you tend to avoid it without thinking. What happened to BigChill is somewhat like that. Ben doesn't know it's time for reproduction but Bigchill's body is aware of it so it did things on it's own, He still battles the bad guys as He is still Ben but he's in Bigchill's form so he subconsiously does everything he do so he can reproduce.

So at that time it's like BigChill gained a separate consciousness based on BigChill's instinct.
