4 and 5 bets, Button vs BB, lag dynamic

[ftavatar]

What are your thoughts when it comes to 4 and 5 bets at 1-2 and above, almost always 6 max when hero and villain are both lagish ( e.g. pfr>25, vpip>22) and have large 3bet/ 4bet ranges?

e.g. 1-2 nl

button Villain(100bb) raises to 7
SB folds
BB Hero (100bb) 3 bets to 25 with KQs
button 4 bets to 72

here if u have buttons range to still be wide e.g. any-pp, A-xS, KQ-J10 and a few naughty suited C's:
i.) is it +-ev to push?
ii.) do you have any fold -ev?
iii.) does villains range tighten to call the all in or is he already commited?
iv.) if u have no fold-ev how deep do you have to be to get some?
v.) what range is suitable for you to push against this type of player to make g bucks?

obv very general and probably hard to answer without specifics but any feedback appreciated.

p.s first post, appologies if it dosen't make sense
