Idiom for doing anything to get what you want [closed]

I'm looking for an idiom which describes a person who does everything to get what he wants even by being dishonest.

People who will do anything to get what they want will stop at nothing.

Here is the definition in the Cambridge Dictionary:

If you stop at nothing to achieve something, you are willing to do anything in order to achieve it, even if it involves danger, great effort, or harming other people:

Four authentic examples from Google:

• Headline: Parents stop at nothing to find cure for son.

• It is clear that he will stop at nothing to win Beck's heart.

• Many people want the live trade ceased and they'll stop at nothing to ensure that happens.

• I recognize that the church must stop at nothing to root out sexual abuse.

The closest idiom for this situation is by hook or crook; also (synonym) by any means.

TFD(idioms):

by hook or (by) crook
by any means, legal or illegal.
I'll get the job done by hook or by crook.
I must have that house. I intend to get it by hook or crook.
