What does にだけにはなるか (vulgar text warning/nsfw) mean?

I am stumbled on the second to left of this sentence.

The character mentioned his revenge failed, and in the last line he mentions
he at least attempted to sleep with a girl. The character is a delinquent who
has recently disciplined by the student council over his lecherous behaviors
with women. He failed to get back at the student council, but I assume he kept
wanting to keep being a delinquent

アイツの言いなりに is "That person's yes man" って may hide an て思う but I don't see what
verb in the middle with the だけ use?

What exactly is にだけに?




I think those four lines form one single sentence. Anyway, the underlying
expression is 言いなりになる, the combination of noun 言いなり + particle に + verb なる,
and other particles (だけ, は and か) are added to it in the given sentence. In
fact, にだけに(は) is ungrammatical. The order of three particles attached to 言いなり
can be either だけには or にだけは with little change in meaning, but never appears に
twice. The character or the author was probably confused about those two
possible word orders and mistakenly mixed them.

ps

あいつの言いなりになる means “to become his or her yes-man/puppet”. The particle か
indicates here the emphasized determination not to do something “I would never
do (something)”, similar to the expression ものか/もんか. The particleは attached to
言いなりに makes contrast; implicitly makes comparison among あいつの言いなりになる and all
the other possible situations, and だけ “only” clarify that it’s the last thing
he would do.
