Place no one wants to go? That guy will! (4)
I believe the answer is:
hell
This might be a double definition.
'place no one wants to go? that' is the first definition.
'hell' can be an answer for 'place' (I have seen 'Infernal place' mean 'hell' so perhaps 'place' could also mean 'hell'). I'm unsure of the rest of the definition.
'guy will' is the second definition.
(contraction of 'he will')
Can you help me to learn more?
(Other definitions for hell that I've seen before include "One of spelt out words" , "Gehenna" , "Tartarus, of myth" , "Abode of evil spirits" , "Devil's fiery home" .)
