You can take advantage of this by using Nazaez Tantra Mantra with Nazaez Tabij Kitab app. You will also get the subjugation mantra as you will get tadbir to kill someone. But think before doing any impermissible act, you will have to give an account in the Hereafter. If you want Najaez Kabiraji app you can use it for good work or benefit someone. For example, helping someone get married, or returning someone's wife if they are estranged from her.
