Why was Mayo so torqued with Foley after Sid's death?

This is something I never really understood.

We all saw Foley lean hard on Mayo to get him to DOR after discovering Mayo was bootlegging for bucks - fair enough - but after the cathartic moment when Mayo all but begged Foley to let him stay, there seemed to be an understanding and respect between them. Again, fair enough.

What I don't get is Mayos reaction when Sid withdrew from the program after freaking out during one exercise (presumably from Linette telling him she was pregnant with his child) and then killing himself after Linette fesses up about not wanting to marry him at all if he didn't become a naval officer. Mayo directly blames Foley and attempts to beat the crap out of him.

Sid even told Mayo that Foley didn't kick him out of the program and it was his own choice to withdraw, yet Mayo takes it all out on Foley and not Linette who faked a pregnancy then dumped Sid after Sid quit the officer's program leading directly to his suicide.

I don't get the rage against Foley.
