I didn’t relish the horror.

Weaponized masculinity portrays the horrors of war as some kind of "test" of masculinity - you'll see this in a lot of fascist propaganda. It's literally what fascists mean when they spew their "blood and soil" bullcrap. It's pretty sick - I grew up in Apartheid-era South Africa, and they brainwashed us like that.

While I’m sure the movie didn’t capture everything, what it showed was horrendous.

The problem I have with movies like Saving Private Ryan is that they don't address the central conceit of the vast majority of "war media" - ie, that war is an activity primarily waged by armed combatants against other armed combatants. This is absolutely not the truth - wars are primarily waged by armed combatants against unarmed non-combatants. This is especially true when we discuss colonialist warfare - it is being literally demonstrated right now in Gaza.

Idk about your point of justification

You remember Tom Hank's little line about "earning it?" The more you think about it, the sillier it becomes.
