This has already been discussed elsewhere. Larian has specifically said that they only added the more evil companions at the beginning in order to encourage players to do evil playthroughs in EA. This was because they felt players didn't explore evil options to any real extent in DOS2 EA.
In other words, the other (good) companions will be added in later stages of EA.
