He dosn't nead them as hosts sinse there is 2000 people onboard and he has every reason to kill them because they are the only ones who would be able to figure out that he is david.
during any time when daniels is hunting it down he could just shut the doar trapping her. he also cares about htis cteature very much. (seen during its birth)
one theory that i have is that he was testing it to see if it was effective enough of a killer. if it was able to kill them then he would create more of the same type but if it died he would have to alter it to make it more dangerous.
this leads me to my last question. why dose david want to create killing machines? he has no use for them sinse he already killed all the engineers (or so he thinks). is he planning on releasing these things on earth to get revenge on his creators? let me know what you think in the comments.
