Stage 1
Due to psychological nature of the subject, usual counter-measures won't give desirable results. Therefore, to mimic its unstable schizophrenic mind we will introduce variable renown method as main therapy.
Stage 2
Initial observation of subjects activity lead us to the conclusion that subject may change its mood on purpose, trying to reach some imaginary goal. In order to stop an end to its hostile personality emerging periodically, we use variable renown method, therefore stopping an end to its activity (subject cannot reach any goal).
Stage 3
We will carefully observe behavior of our subject. If hostility toward other test animals continues, we will be forced to put it to sleep, mark its cage with an X and throw it into our deep storing facilities. From now on, we will perform detail inspection of other subjects to make sure this never happens again.
