well i guess it not really killing it is is just deleting all the code inside it and replacing it
what i have done is use this line to delete the code open("main.py", "w").write("I replace with a bit of new code") but before i delete all the code i save that code in a txt file with open("backup", "w").write(open("main.py").read()) and if the user want to revive the program or restore the code it can grab the all the stuff from the txt file and put it in main.py
So it will give the illusion of the program dying
