Swen practically confirmed that Jaheira is more neutral than good, just as many of us here said. So the 10 companions are: 4 evil (incl. 1 to be redeemed?), 3 neutral, 3 good. Among the subset of 6 origins it is 3 evil, 2 neutral, 1 good.

Plus an evil origin skin for the custom PC.

Pretty clear where Larian's preferences are at.
