That's not what I am saying. At all.

What I said was that Moiraine was prepared to defend herself at any moment, because of her mission. She did not indiscriminately start attacking people because of it, but her life has been in danger more than once, and often not on battlefields. Recall that Lan mentioned carrying her all the way back to the Tower with an arrow in her back, and her doing the same for him. Considering the nature of her mission, I believe they were in situations where anyone and anything could be an enemy.

You'll also recall that when she met Balthamel and Aginor, she didn't wait for them to attack - the fact that they were Forsaken and were in front of her was enough for her to start fighting them with killing weaves.
