Is the intention to kill considered as killing, or is the desire to kill someone, such as a soldier who confiscated a motorcycle, considered as if it were killing?

The phrases mentioned in the question do not necessitate killing, nor does contemplating it to oneself. Inciting unlawful killing is not permissible. It is not permissible for someone who has animosity or has been wronged by another to kill them; rather, they are permitted to repel and prevent their aggression. There is no accountability for contemplating killing to oneself as long as it is not acted upon or spoken of, based on the Prophet's (peace be upon him) saying: "Indeed, Allah has pardoned for my Ummah whatever they whisper to themselves, as long as they do not act upon it or speak of it." It is advised to continue seeking knowledge, maintain congregational Fajr prayer, and regularly recite the prescribed remembrances.
