Remove an application server profile - WebSphere Application Server 8 (beta)

I used the following to remove an application server profile (the install did not go well). Then, the system became unstable. I had to reinstall the whole package.

manageprofiles.sh -listProfiles
manageprofiles.sh -profileName -delete appsrv01

I am not sure if this is the right way to remove an application server profile.
