born to be
为...而生
是个词组
所以这个原句没错

看你想说啥，was:他以前是个当总统的料理他 is:他生来就是当总统的

The baby has just been born. And you can tell that he is gonna be the future president. You say "He is born to be a president ".

You need to take "context" into consideration before you ask that
It's absolutely nonsense to tear the sentence apart from the context

当事实处理

同吧主观点，还是用过去式吧

这个 born 是形容词，不是过去式。

be born to be生来注定要成为
be born and bred土生土长
be born of生于
e.g.:He was born of a rich family
＝He was born with a silver spoon
含着银汤勺出生，喻指生于富贵人家，出身高贵
bring up养大/拉扯大
