I agree with your disagreeing (at least in theory!). :D
I absolutely agree with the bit of your comment I've bolded, and have probably argued that myself in the past, but in this case I choose to see the Beale situation as I describe in my above post. I can sum up the reason why in three initials:
D T C
He made such a monumental c*ck up of the storyline and there were so many contradictions that it just doesn't make much sense whichever way we look at it. I choose to believe the Beales are still remorseful because the suicide attempt and perjury fits more or less with their many years of previous characterisation. On the other hand, their apparently complete lack of concern about Max since he was banged up doesn't fit in the slightest.
DTC was notorious for ridiculous and sensationalist storylines that had no long term consequences for the characters, so I see this as just another example of that and believe the psychological aftermath for the Beales would have been handled very differently in more sensible hands.
I know you'll never see it my way though and plenty of viewers agree with you. :p
What will be interesting will be Ian and Jane's reaction when confronted with Max. Will SOC choose to portray them as remorseful and redeemable or as hard-faced lost causes?
