That's not what "the right to life" means. There are lots of policy decisions which have tradeoffs that result in more or less life lost. For example, the government could require that all car engines have a maximum speed of 25 MPH. That would empirically reduce the # of lives lost in automobile accidents, but society has judged the tradeoff (in terms of convenience, transportation time/cost, etc.) to not be worth it -- and that tradeoff does not constitute "violating the right to life".
