[Avodah] dovid and midos (us/them)

[Harvey Benton]

dovid cursed the ____ [cutheans???] that since they did not have the
midos of rachamim by accepting his apologie(s-)? of what his army did
(killing x numbers of thier soldiers, they were no longer (forever??) able
to enter into k'hal yisrael?
?

my questions are:
1. what the army or generals do or don't do do not represent every member
of a cuthean or other society. what if generations down the line areue
converts???

2. we seem to have the same issues nowadays with certain other peoples
(not to be named) that they kill us and commit other atrocities
against us, while we accept their wounded and even accept their special
children/needy hospital cases into our country (while our own people go
hungry and even homeless (3 killed by fire in Haifa a few years ago.......
