I personally think that the Bible is a mixed bag.
It has everything one needs to make someone a horrible person.
It also has everything one needs to launch a spiritual journey that could make one a compassionate and caring individual.
The problem here is that horrible people will most likely be attracted to the horrible in the Bible, and the loving people will be attracted to the loving in the Bible. Just as with Luke (that is, Luke Skywalker), you bring something of yourself into the cave with you, and that plays a significant role in shaping what you get out of the experience.
That's even if one has a transformative experience. Some of the biggest jerks on the planet are born again Christians.
Ironically, the Bible contains the keys to both heaven and hell.

The question is
how it creates horrible or good people. This is a ridiculously complicated question, but I think that the Bible can be blamed for good or bad insofar as it
commands or instructs goodness or badness -- not, take note, the commandments of groups of people in the past (e.g., God supposedly commanding people to commit genocide), but commandments that stand, basically, for the reader of the Bible in his present life.
And I don't think the Bible is bad with this consideration. Nonetheless, it can be pretty vague or ambiguous as to what something means when it's commanded, and many people have misrepresented the Bible through incorrect theology and twisting of certain verses.
And the destructive ideology Kierkegaard is critiquing when he loathes Bible societies is the idea that all you have to to do to be a good Christian is read the Bible, add a little prayer, and you're good to go. This is an instance of instrumentalizing the Bible rather than actually reading the Bible -- because when you do that, you're forced to accept or reject ideas such as "die to yourself" or "love your enemies", or in the deeper Kierkegaardian sense to live a life of faith that transcends ideas and moves into a moment-by-moment relational life with God who gives commandments via the Logos.
If we're going to put it into a process, I think it goes something like this:
A person is born into a Christian society and is forced upon Christian beliefs and rituals, including going to church, where he is told to read his bible, pray a bit, but whatever he does
it's all okay, because grace covers everything. Nowhere in this process does he really "own" his belief, given that Christianity is culturally mediated to him; it's handed down to him like any other ritual. This "grace" basically has the meaning that "whatever you do, you'll go to heaven when you die," which crystallizes a type of life that has minimal changes in consideration of Christ: often these changes translate to
standing up for the idea of Christianity (i.e., cultural hegemony and tribalism) and speaking slowly and considerately when God is brought up in conversation. It's this broader type of bad theology that K has in mind in condemning Bible societies, and this theology could only be possible if 1) the Bible were unclear enough to allow for an interpretation that works this way, and 2) people were unwilling enough to be actual Christians and look at what the Bible really says.
