This is just to clarify a few things about the way I handle Wade's crazy.
So, in general, it is canonically accepted that he's a bit (a hell of a lot) insane. And I do tend to stick to this when I can.
But it isn't always obvious, and I'm going to explain why.
So, when I first flirted with this character I was thinking about the best ways I could portray him like he is in the comic, but also as a (mostly) human whose sole purpose isn't always to entertain.
What I came up with was the idea that Wade is, most certainly, annoying as hell, but the crazy comes and goes.
The most common deciding factor in this is who he's with. There are certain people who bring out the sanity in him and, alternatively, there are some that trigger the insanity.
But, like most things in life, it isn't concrete.
He can be perfectly agreeable with a person one day and (for whatever reason - be it alcohol, sugar, a bad day, boredom) he can be utterly mental the next.
Even more commonly, he can be acting pretty normal and thinking about attacking children in his head.
I will always do my best to make him fun and entertaining and well written, but if I ever slip I am sorry and I hope to make it up to you in future.
