"I can get my pleasure from the flubby vagina hole, but the planet's gonna pay for it.."
Perhaps he never had a choice about impregnating the girl. Perhaps he was predetermined
to create the seed that will carry his legacy.
Or perhaps it was indetermined. It was just a random neuron spark in his brain that found him having unprotected sex with the nation hoe. It's not his fault, his action was random, indeterminate.
The libertarian would say that he does, in fact, have the ability to change it all. He may take the responsible, immediate path (find some means by which to abort the seed, a hail mary perhaps). If that proves unsuccessful he could do the responsible thing, raise the child right, etc. I find this the least likely outcome.
I've been leading more towards determinism lately, so I say he was determined.
