Killswitch on the messenger

Goodmorning frends

Im thinking to ask for a killswitch.
When you hit this, the complete app is off the phone without any trace.
I ask this for people in moslim country’s that read the Bible or for homosexuals in country where that’s strictly forbidden.
69 country’s with jail, dead penalty, life long jail.
I was wondering what your thinking is off a killswitch so our friends in these country feel more secure with the messenger
