In English we often use an infinitive with to to talk about a person’s purpose.
We can also use 'in order to' or 'so as to'.
'So as to' and 'in order to' are more common before verbs like be, have, know etc.
Before a negative infinitive, we normally use 'so as' or 'in order'.
Notes for use of infinitive of purpose :
We say I came here to study English NOT I came here for studying English OR I came here for to study English.
We can use for + noun to say why we do something.
