Yes and no...how to explain...
At some level, yes, as I do derive pleasure from the sense of intense suffering of the lee due to the tickling. Knowing that it's unbearable, and appreciating that sensation myself, I love knowing what they are going through and being the cause of it. However, it is not indiscriminate sadism. If they legitimately don't want to be put through that, my feelings towards it are short-circuited, so to speak.
The reason I say no is because I've ran into the usage of the term "sadistic tickler" so much in recent years that it hits me differently. Often in chat, it's the first question someone poses to me. It's like a keyword that certain people have started to associate with a very specific image or situation in their mind, or some kind of standard to go by. It's difficult to describe exactly what I mean, but that's kind of the impression I get, and it leaves me feeling like it's not a phrase I'd use to describe myself so as to not give others the wrong impressions or something. It's probably a problem that applies to a lot of words or phrases used to try to capture how someone identifies or feels about something. It can easily become charged, or hyper specific, and lose its more flexible utility. Maybe this has just been my experience, but either way, it just feels weird to use the term most of the time these days, and so I seldom do.
More often, I usually just say I like extreme or intense tickling, but also enjoy other types as well.
