'For the third time, Charity burbage revolved to face Snape. Tears were pouring from her eyes into her hair. Snape looked back at her, quite impassive, as she turned slowly away from him again.
'Avada Kedavra'
The flash of green light illuminated every corner of the room.'
p18 Chapter One

I wonder what level of internal conflict Snape would have been feeling at this point?
