Abe was slightly bewildered about the future of Japan. This sinking ship might not be salvageable with simple repair and refurbishment any longer.
What should he do next? Or what should he do in the future?
Perhaps looking out for his own interests is the best plan?
Yes, all a politician needs to do is to look out for his own interests, whether it's for the party or his own family. Their personal interest is what matters the most.
Whether this behavior will plunge Japan into an abyss or let the citizens of Japan pay the price; does that really matter?
Even if he saves Japan, so what? One of humanity's flaws is forgetfulness, especially towards the benefactor. Look at Churchill, who contributed significantly to the United Kingdom; wasn't he immediately kicked out of his position without hesitation once the war was over?
