And..there is a nice piece of Reb Elchonon z”l on the gemara where Chizkiya did not want to have a child becuase he knew he would not be frum – the navi said to him – behadi kavshei derachmana lamah lach – Reb Elchonon says this is a klal – we can’t know what the outcome of our actions is ever going to be and it’s not our business – our chiyuv is simply shemiras hamitzvos
