It is actually intentional on my part, because I feel that Howard has less of a moral compass than Tony does and would be more focused on progress than the damages of that progress. Particularly because he's specifically mentioned to be a weapons manufacturer in the movie, it means he would be involved in the arms race that when on throughout the war (and other sources in MCU say he was part of the Manhattan Project too). While Tony was more horrified at realizing his weapons were being used by terrorists, Howard would see it as a natural consequence of weapons existing. I wasn't sure how it was coming across, so I'm glad to hear that it's noticeable!
