intemperance is one of the most contemptible and loathsome habits into which one may fall.
it is also one of the most dangerous.
it springs from the lack of self-control, and it destroys what little self-control may still exist.

what little self-control may still exist가 destroy의 목적어가 되는거 맞죠?
목적어자리에 명사가 와야되는데 may still exist는 뭔가요? what little self-control 수식하는건가요?
수식하려면 control이랑 may사이에 that(주격관계대명사)써줘야되는거 아니에요?답변부탁드립니다.
