For me (as a lawyer - albeit not a criminal one) the big issue is that you can't ride two horses in this kind of situation. So you can't have two defences which is essentially what OP has been trying to argue
Firstly that it was self defence and then he went down a route of saying that his actions were involuntary.
Barry Roux tried to get him back on track somewhat by asking him in re-exam what, if any, his intentions were. But the whole thing was such a clusterfuck and OP's credibility so badly damaged, that he's not really been able to succeed.
So, the issue now is that OP doesn't actually have a clearly specified defence. The Judge can't make the facts fit what she thinks has happened and then decide what his defence should be. Her only option really is to go with the prosecution's case because she does have to make a finding and OP hasn't actually really put forward a credible defence.
OP's team will lead lots of expert witnesses but they are just there as corroboration and there is no clear defence to corroborate. So they are very limited with what they can do to assist.
It really is quite awful for OP as I think he is so lacking in credibility at the moment that there is a very real risk that the Judge could disbelieve him on the intent part and find him guilty of murder.
If not, then I think he will absolutely be found guilty of the lesser charge. His "two defences" mean that he has actually not pit forward one credible one
