I was a lot more sarcastic in my young years (believe it or not). I toned it down simply because it hurt people unnecessarily - and it was often merely an ego-prompted thing.
(But I proudly backslide, when it’s truly useful...it’s sorta like swearing.)
My trajectory was similar.
With the exception of the backsliding, thankfully.
I tend to recall all of the bad things that arise out of the practice and then find some other way to express myself that doesn’t involve the “net negative” calculus that is always associated with sarcasm. It’s hard to describe all the reasons why it is just bad. Badzo.
