I don’t get why many Venom adaptations lean so much into mind control

Many Venom adaptations have the symbiote completely took over the host that is just a meat puppet and has little to no agency and it’s a concept that doesn’t fit the character at all. Like the whole point of “We are Venom” is because is the host and the symbiote together. The “we” doesn’t make any sense if is just the symbiote. And it makes the whole having a host pointless because the host ends up just being there so the symbiote can walk up to two legs.
