Lives as a whole have to do with all existing things and it is it. Yes, it is true but i will advise that generalization is not good and it should be avoided in nature. Whenever something happens, the doer(s) of the action(s)should be held responsible only. His/Her/their nation, tribe and so on should not be considered in order to have everyone implicated in the act just because of an individual who has caused his or her problem(s) or by himself or herself. People doing things wrongly have nothing to do with their nations,or tribes. These people should be talked to or be dealt with individually; not because lives have to do with all existing things so people should just conclude on any happenings by generalization to have other mocked at.
Generalization had caused and is causing a lot of problems in this world and this really needs to be given a serious attention.
