You really do get a mulligan on goodie kill #1 unless you role-play it poorly or there's reason to believe you were truly negligent.

It does make it more likely you're punished in some way for #2.

That said, you're not evaluated in a vacuum, and both the individual circumstances of the kill *and* your overall contribution to the cabal would likely be considered.

Some other thoughts:

1. You mentioned maybe goodies aren't your thing. It's worth noting this is really only a Fortress thing. While no good-aligned character should be blasé about killing innocents, unless it's excessive you're probably only going to face repercussions if your goodie is in Fortress.

2. Might want to lay off using the term "darkie". It has an unfortunate prior meaning outside CF.
