Should we use technology to restore species that have been extinct because of humans?

I think we human should not use technology to restore species that have been extinct it because sometimes survival of the fittest it because according to Breanna Draxler on Discover magazine , he mentioned the following 5 factors:

• Animal welfare: People could be exploiting animals for solely human purposes, and may cause individuals of the de-extinct species harm.
• Health: Species could carry retroviruses or pathogens when brought back to life.
• Environment: De-extinct species would be alien and potentially invasive; their habitats and food sources have changed, so their roles in these changed ecosystems could be too.
• Political: De-extinction may change priorities in other fields of science, such as medical research and the conservation of currently endangered species.
• Moral: Is de-extinction playing god, or just plain wrong? It may also have unforeseen consequences.

My opinion:

• Modern ecology:Because their attack may cause damage to modern ecology.

So the reasons above make me disagree. We use technology to restore species that have been extinct because of humans.
