"Science" is really just a method of trying to understand the world, via "scientific method" - that is, querying Nature rather than just making assumptive pronouncements about it. The problem is when it - or rather, scientists and scientific organizations, and scientists themselves, become subverted/corrupted, despite the checks and balances on itself it's supposed to have. Example - Descartes. Not a scientist, but the propaganda he spewed on behalf of sadists passing as "scientists" stuck as "science" and has caused more death and suffering than hitler, stalin, pol pot and all those assholes combined could even dream of.
