The pedal axle is hardened steel, so you'll have a job cutting it off. and I wouldn't hold out much hope for drilling either.
When you say its 'squint', do you mean its not straight? If that is the case, its likely that it has been fitted badly and the cranks will be broke.
What kind of cranks are they? Do they have any markings on them?

Easier to get pedals off when the crank is attached to the bike bob. loads more leverage!
IME if the pedal has been forced into the crank arm, considering the pedal axle is toughened steel and the crank arm is alloy, there will now be a new thread cut into the alloy crank arm. So, if you can get the pedal out you'll have to try to find the old threads in the crank arm, which is unlikely.
I would start looking for a new crankset

Not a hard job, but you need the tools. and a rough idea of what you cranks you want/need.
AT least four differing cranks types it could be.
Isis, Square taper, octalink or external Bottom bracket.

Not only do different cranks require different types of bottom bracket they used to require different length axles too.
A new bottom bracket is normally under £20 so i wouldn't worry too much about having to change this as well. (although hopefully you wont need to)
When you use a crank puller make sure the puller is fully and securely screwed into the crank arm before you start to wind the bar in. It's very easy to strip the threads in your cranks.

When I asked how to do this before not one single person knew a method that worked that didn't involve a blowtorch which I didn't have (might not even have worked if I did, we'll never know will we), but the thing that DID work was to put the crank arm on a bench and whack it hard with a heavy hammer on either side of the pedal axle. It was then possible to turn the pedal axle with a long pedal spanner with the crank arm in a vice.
i.e. whack here:
the purpose is to ever so slightly ovalise the hole in order to break the seizing.
It goes without saying that this method is not advisable if it's a carbon crank.

~Bonj, telling someone to hit parts of their bike with a hammer doesn't help them fix their bike. It does tell them how to break their bike, that is why no-one suggested 'your' method.
so how much do you want to bet that you can break a crank arm by hitting it with a hammer in that way...I think Steve's just offered himself up for a little wager here! He wants to get an alloy or steel crank, then post a video up on youtube of himself screwing a pedal axle into it, laying it on a bench, then taking a hammer and breaking the crank arm with it. Actually breaking the crank arm, with one hit from a hammer, but thus doing the public a service by showing how easy it is to break your bike by following unconventional advice from the likes of the evil bonj.
so how much do you want to bet that you can do it then steve - tenner? twenty? or aren't your puny arms up to the task? come on, the public need to know just how stupid I am to suggest such lunacy.
, i've reported it. as you should know?
