I agree with Raving Dork - a good character could do all this except the torture.
I'd say the torture is an evil act. However, it is not like he did it for fun. If I were one to give "points" to a character based on their actions, this would certainly merit fewer "evil" points and definitely not a sudden change of alignment if they weren't already evil.
Law vs. chaos - just because the rogue is causing major death and destruction doesn't make him chaotic. It just makes him effective.
