IVF is a sticky wicket. If the embryos are kept frozen and not destroyed, I have no real problem with that. The other is a point where I have trouble reconciling the idea of life begins at conception with human intervention for said conception. I really don't have a conclusive answer regarding that for myself.
This is why the Catholic Church opposes IVF. People give the Church a lot of crap over being “anti-sex”, but there’s deep logic behind its positions. If you believe life begins at conception then a system that relies on causing conception a dozen times over and then leaving all but one of those in Limbo (until they inevitably perish just because no cell can be preserved forever) or destroying them outright is mass murder of innocent and defenseless lives for the convenience of others.
It’s also the logic behind “sex should be limited to husband and wife” because that is, as studies have shown, the ideal environment for raising children. This isn’t to say it’s the only way it can be done, but, to draw a correlary... just because some kids will succeed even in a failing school, doesn’t mean we should make a failing school our ideal.
As to the Pascal’s Wager... the way I’ve always heard it expressed it not “if you’re wrong... Hell” it’s that best case for the believer is Heaven and worst is non-existence after death; best case for the non-believer is non-existence after death and the worst case is Hell. Therefore since the believer’s worst case is no worse than the non-believer’s best case, you’re better off believing whether it’s true or not (particularly since those who hold to the charitable and benevolent lifestyle espoused by believers are also generally well regarded during their lives as well).
In other words, even if the believer is only right on a natural-20... they’re critical fumble is no worse than the non-believer’s critical hit.
For an added bonus, the Catholic Church holds that, to the extent something is true and good, it is of God, means that even those who guess wrong on the “which specific set of beliefs” part of the test still get positive credit towards the best possible believer result (and just like the “ideal conditions” for raising a child, the Catholic position is that The Church offers the ideal conditions for reaching Heaven, which is why you should pick them over other potentially viable, but less ideal, conditions).
Basically, if you’re coming from a Catholic perspective, you’re still better off sincerely believing in Odin (the Norse religion still holds truth, justice, charity and courage to be virtues... so at least points to God) than believing in Atheism (it’s all just deterministic chemical reactions with no meaning but what our delusions of sapience tells us there is).
My own position on Abortion is pretty simple; I am for life in ALL situations. I am against abortion, the death penalty, euthanasia and all other forms of killing save for immediate self defense (and no... preemptive strikes are not immediate self defense). Likewise, food and water is not “life-support” (it is most typically a convenience vs. feeding by hand) as opposed to ventilators and the like (and even then, I’d want a pretty high standard that such life support would be both indefinite and not desired by the person on it for me to say that withholding it would be acceptable).
I am also against killing animals except for food and immediate self-defense and, even then, it should be done in as a humane a fashion as possible (no strangling or bleeding out or other savagery) and we should give thanks to the animal that died to sustain us.
I try to be as consistent as possible on this. It’s why I started opposing the death penalty about twenty years ago. It’s much easier to argue “Life in all cases” than “x degree of guilt deserves life, y degree forfeits their life.”
Needless to say, in superhero games I skew very hard towards the Superman/Batman end of the spectrum vs. the Wolverine/Deadpool end. Even in Rifts my favorite character was a Ley Line Walker who specialized in non-lethal spells for combat (and non-combat magic in general) and often ticked off some of the players who just wanted to shoot people because they couldn’t keep their good alignment if they killed helpless foes (on the other hand we made a fortune off all the fully intact armor we stripped off defeated foes).
