how to use" can't?

[whatiswhat]

hi folks
I saw 2 weird sentences.
they are weird to me please kindly tell me if they are correct or not.

1)
I cannot to do it.
2) I cannot not to do it.

As I know the modal verb" can" or " cannot" is followed by an adverb or verb.

Thanks in advanced

Yes, I think to shouldn't be there in either sentence:

0 on "cannot not to do it"

But show us the links to those sentences anyway.

"Can" is not followed by "to", except in situations such as this one:

As I said from the start it's vitally important that we do everything we can// to defend Hospital.

The key phrase there is "do everything to defend the..."

Normally found with:

all/as much as/everything we can//to
