Hosts are the member(s) of the system who front the most. They tend to have some level of power but like everything else, it depends on the system and its members. The host, being the one who lives in the body the most, must manage its members and their system. If a member does something wrong they must take accountability for it, DID is not a way to not take responsibility, even if it was another alter who did it; Accountability is important.
