Whyever

Whyever would someone do that?

You can use it whenever you want and whyever you want.

Whatever we do, and whyever we do it, does not every motive originate in self, and does not every act proceed out of the individual's instinct for self-fulfilment ?

Whyever they began, there was no perceptible wolf at their door.

"And whyever they were doing it, they were the ones responsible for what happened to her and all of the rest of my friends in the first place."

I don't care what you want. Whyever you're here, please go away.
