I'm not sure if this is correct. mainly my perspective. I would write animal testing is morally wrong due to the fact that they weren't put in this Earth to be tampered with. everything in life has it's own purpose and who are we to decide whether or not a animal should be tested on due to some people feeling like they're superior and willing to interfere with an animals life just cause they want to figure stuff out. animals have feelings too. hope my opinion helps.
Answer:sibling rivalry
Explanation:
What is sibling rivalry?
This is an animosity and fighting between sibling that occurs due to the arrival or birth of a new child in a family .

The older child may feel like their parents like this child more than they love him or her because of this they may act spiteful towards their sibling .
To them this may feel like the only way to take out these frustrations by being mean to their siblings.
