The weak can stand in the society with their heads held high, but for that we need some support. Parasites or weeds harm others, but the weak never compare with parasites or weeds. For example, not everyone is perfect in everything, he will do better in the future if he gets help on the weak. Think about a herb plant! They need the support of another stick or tree to grow. After a while the herb will come to fruition but the plant will never leave the support the plant had and never harm the supported tree or stick. Love and gratitude exist here.
