I agree with the rest of what you said, but I don't see how this contradicts what I said. He was clearly shown as enraged and especially in the case of Clovis, clearly tapping into Dark Side emotions. When he force-choked Poggle the Lesser, it was a little bit more gray since he was trying to save lives, but I'm pretty sure the intention was to show him dancing closer to the Dark Side, utilizing torture rather than looking for other options.**
I would maintain that it is a purely offensive move*, so while it can be linked to good emotions, the very nature of the power tends more towards dark. With something like the force-healing, it works either way and you can tap into either the Dark Side or the Light Side.
*Especially when directed against defenseless being such as Poggle the Lesser, who was unarmed, cuffed, and in a cell.
**Going the quick and easy route to power of tapping into the Dark Side.
