Helga's Makeover - Of what I recall they find the boys spying and when they catch them basically just try to give them makeovers a anything serious as pay back, not evil if I recall right just a jerkish pay back.

Operation: Ruthless - Doesn't harm anyone from your ow description just doesn't want them to get together which isn't evil just an antagonistic.

The Sewer King - That's not evil just being an ass.

Magic Show - Not entirely sure what you even mean and what little I made out of it is her mildly threatening.

24 Hours to Live - Not evil to want to postpone a fight between two people.

Arnold's Halloween - That's at most being a jerk to like scaring people in a costume not villainous.

Biosquare - Getting mad and yelling isn't evil and throwing something in anger isn't uncommon in kids. Nothing described here goes over into villainy.

Girl Trouble - Minor bullying and Jeremiah behavior of what I remember not actually crossing into villainy.

Love and Cheese - You're trying to make it sound like she wanted to kill or severely harm them when it's more "I don't want to hit it off" by ruining a date.

Big Sis - Honestly don't remember this episode.

Parents Day - Not remotely close to evil or villainous.

April Fool's Day - Not evil just a jerkish act and mean spirited prank. She isn't trying to do anything more than take advantage of his guilt and then reveal it was a prank for what boils down to minor embarrassment.

Ghost Bride - Mean spirited prank with no intention to hurt anyone. Not villainous.

Given only one actually might fit of your list no, one incindent in a rather long run isn't enough especially since I highly doubt she wanted to harm her sister, she doesn't generally like her but makes it clear she cares for her wellbeing at times despite their differences.
