How to kill a process with batch file

hey, i just experimented around. task manager(what i tested) cannot be killed except by it killing itself. System.exe is always not killable, because users claimed that by using task manager ( which at the time could kill anything no matter what the process was) was BSODing the computer. MEMZ-destructive cant even stop task manager. and about that "AMPPSS.exe" app, I would try using this code in python 3.9.3: (or if it doesnt work then then either you are or im using an incorrect version of python)

def process():
      
    name = ("AMPPSS.exe")
    try:
          
        for line in os.popen("ps ax | grep " + name + " | grep -v grep"): 
            fields = line.split()
              
            pid = fields[0] 
               
            os.kill(int(pid), signal.SIGKILL)

        print("Process terminated")
          
    except:
        if (pid).terminate = (True):
             os.open('DONE.txt')
   
process()
