Disliking someone is a reverse attraction to them. If you can't let your anger for them go, then its either out of habit or negative attraction. We call these people infamous and so forth.
Since tickling is silly, cute, and sometimes sexy behavior, to commit it against someone you don't like would take it from being what it is into a form of physical abuse. And if you're honestly doing it because you dislike them, then it implies torture under a non-consensual situation, which is sick and criminal.
As you can't just walk up to people, tie them down, and tickle them, or just expect them to take it (they could always defend themselves if they feel they're being accosted or assaulted), then its only in fantasy that this situation occurs.
And if you're fantasizing about these people under your control, and adapting it to meet your fetish needs, then, in one way or another, you are attracted to this person.
If you dislike someone so much that you'd want to take your tickling and turn it into something its not, then this person must really be worth it. If in retrospect you say thats not true and they aren't, then why are you bothering your mind with them?
Thats how I feel about this.
Theres no point to wasting a fantasy on someone you don't even like, and even less a point to even trying to physically do something about it. If you want to or have done something about it physically, then perhaps you didn't dislike them afterall.
