We can take some lessons from the story of Robin Hood. He steals from the rich and gives to the poor. No matter how pure his intentions are of helping people in need, because he used a method that was haram, those deeds would not have been accepted from him. Even if we want to help someone, if our method of helping them are un-islamic than those deeds would be of no help for us.
If your intentions are pure, you would want rewards and blessings from Allah. So why not use the right methods. Than the help you would do, would be lasting, and even solve the issue.
