Compared to Kylo Ren’s outbursts Vader cracking glass of a Star Destroyer doesn’t really count as a tantrum. Also Vader wouldn’t just shrug off at the fact he has a son. That’s just not who he is.
Well, “tantrum” might have been a poor choice of words, but it is a bit too similar to the end of ROTS for my taste. One of he things that I liked with old EU stories is that they would acknowledge Vader’s feelings, but without having him smash stuff in the process (SOTE is a good example of this). He tended to keep it to himself.
I personally just find the more ambiguous pre-PT Vader more interesting. But I do agree that Vader’s reaction in the old Marvel comics is, retroactively, somewhat bland. But even that reaction is up for interpretation.
