Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN

Hope the discovery and invention is good for the human welfare but what about those invention and discovery that bring the living species and nature at stake. I'm not becoming skeptical and criticizing the anti-matter but why there is a need to discover that particles which has a consequences of releasing energy that is more that atom bomb.
As we have seen that the bomb( hydrogen or atom) has nothing to do for the good sake rather to make one country dominating into another or making domination. Thus this is not the case of human welfare aswell as the universe other species living in a sound world...
I'm not pessimistic but this things are really more devastating from the living perspective  but may be it is good from the scientific perspective. Hope this discovery  can bring no problem in near future.
