Sure. This is massive spoilers, of course.
First choice:
Reputation greater than 6: But I am not evil! I am a force of good and
justice!
Reputation 6 or less: You sound like a hypocrite to me, sentencing those
you have no right to judge!
Second choice:
You would make us out to be victims of circumstance rather than masters
of our own destiny.
Third choice:
You don't honestly see yourself as the force of righteousness in all
this, do you?
Fourth choice:
Look at the suffering you have brought to Amkethran! Your monks
terrorize the innocent at your command! You hire soulless mercenaries
that cut down the innocent at the slightest provocation! And all for
nothing! You call these the actions of a good man?
Fifth choice:
Wisdom 14-, Charisma 15-, Alignment Good:
And what becomes of Melissan, then? Is she free to raise Bhaal and
complete her plans?
Wisdom 14-, Charisma 15-, Reputation 18+:
And what becomes of Melissan, then? Is she free to raise Bhaal and
complete her plans?
Wisdom 15+:
And what becomes of Melissan, then? Is she free to raise Bhaal and
complete her plans?
or:
You don't have to do this, Balthazar. We don't have to fight each
other.
Wisdom 14-, Charisma 16+, Alignment Nonevil:

complete her plans?
or:
You don't have to do this, Balthazar. We don't have to fight each
other.
Sixth choice:
Wisdom 15+:
And you're going to stop her alone? Have you given any thought to the
fact that maybe you've been helping her all along, that she's been
playing you like a harp?
or:
Alaundo's prophecy does not mean the Bhaalspawn must be destroyers,
Balthazar! It also means we can stop the prophecy from becoming true, I
know this!
Wisdom 14-, Charisma 16+, Alignment Nonevil:
Then we should fight her together! How do you know she still can't
summon Bhaal...everything you've fought for will be for nothing!
or:
You can walk away. You can do what's right, Balthazar, what you know to
be right instead of what you've resigned yourself to.
Wisdom 14-, Alignment Good:
Yet another death added to your tally? And what then, once you kill
her? Once you have all that power and it's yours alone...you think
you're going to resist that?
Wisdom 14-, Reputation 18+:
Yet another death added to your tally? And what then, once you kill
her? Once you have all that power and it's yours alone...you think
you're going to resist that?
Seventh choice:
Join me, Balthazar. Let us fight Melissan together, instead of doing
what she wants us to.
