Question

Are the grammars of these sentences correct?

These are parts of my essay and I felt insecure about it's grammar

1.He just aligned his self to the gang as protection
2.He needed to suck it up in able to survive the cruel world of highschool.

3.This loser was useless as before because now he is a wife beating businessman.

4.He can’t be stronger to any man so his only way to conquer is to abuse a helpless woman who happens to be his wife.

Answer 1

1.He aligned himself to the gang for protection.
(Though I would phrase it like this: He joined the gang in order to protect himself.)

2.He needed to suck it up in able to survive the cruel world of highschool.
(I would replace the word 'suck it up' if this is a professional nonfiction essay. If it's fictional story, however, then it can stay as is. For a wider selection of words, check out www.thesaurus.com)

3.This loser was useless as before because now he is a wife beating businessman.
Correction: The loser is as useless as he was before, only now he is a wife-beating businessman.

4.He can’t be stronger to any man so his only way to conquer is to abuse a helpless woman who happens to be his wife.
Correction: He is a weak man, and his only way to appear stronger is to abuse his helpless wife.

Answer 2

I feel your sentences would be better when put this way. And, if you are relating something that happened in the past, as in stories, then, you should only use past tense, except when a person says something, as inside double quotes.
1. He just aligned HIMSELF to the gang FOR protection.
2. He needed to suck it UNABLE to survive the highschool cruelty.
3.This loser was AS useless as before, beacuse, he WAS THEN a wife-beating businessman.
4. He WASN'T stronger compared to other men, so his only way to conquer WAS to abuse a helpless woman, who happenED to be his wife.
