Enemy or Friend?

I can't understand why we (the children of our ancestors) accept the pharmaceutical drugs, religions, food products, medical training and guidance for our hospitals, political and legal system, and educational materials and school curriculums for our kids from the people that defeated our ancestors in battle/war and trickery to colonize our country and used our ancestors for the slave trade! Should we consider the descendants of the enslavers our enemy? Should we trust their intentions on providing us anything for our benefit, or should we really take caution on anything provided to us by the descendants of our enslavers (e.g., covid vaccine, IMF loan, USAID, malaria vaccine for babies and pregnant women, etc)? I noticed lots of vaccinations and medications, religious books/bibles, and school training materials teach everything least beneficial for our upliftment and technical growth in the world of STEM, from these people. Should we consider these people the enemy and act accordingly? Or should we trust them and accept their givings as good deeds for our people with the best intentions?

Please help me understand why they are not treated like the enemy in Ghana, and many other African countries! (Keep your friends close, and your enemies even closer!)
