Hand from early in 55: MTT on party

[DMACM]

I play tons of stts and I want to start doing more mtts so I am new to posting here.

Villan Button ~1000
Villan CO ~1000
Villan BB ~1000
Hero EP ~825

Hero raises 125 preflop 3 callers

4 way flop K T 3 rainbow, 500 chips
Hero pushes 700, Villan Co calls, Villan Button calls with QJ, Villan BB folds

I dont like villans call preflop, but is it justifiable on the flop? He is calling 700 to win 1900, and probably has a 20-25% chance of winning. However, is it worth it for him to take this negative ev gamble because its early and he can gain a big stack? Would it be a call if he were calling 700 to win 2200?
