The context is that Hasan's view is that "as long as he is Anti-israel, then it's worth people to vote for, the priority is ending support for the genocide and the Israeli state on a political level, regardless of the personal background of the politician". To my knowledge the rest of his commentary on Platner was analysis rather than outright support from a "harm reduction" perspective.
The "I dont care" is not exactly a literal "I dont care about the bad things he did, and im perfectly fine with him as a candidate" it is more "I have discussed this at length on stream in my political commentary, and some of you keep coming at me from my left about it but 'I dont care [about the commentary from my left flank on this topic] anymore because I've had this discussion every day'". He is addressing the chatter more than the topic in those clips, by my reading.
It doesn't radically change the clip(s), but I don't think it is an accurate representation of his position. I am not saying that I personally agree with his position either. Totally fine if you want to flame him with context. I also want to point out that this clip is not evidence of him requesting donations or campaigning with him as implied by the QT, but that isn't directly relevant to our discussion.
It is very easy to clip hasan like this from the right or the left, so I would not weight it too heavily when you see it unless it is an unedited 30+ seconds.
